“Elena, wait a moment!”
I had already pressed the elevator button when I heard my neighbor’s voice.
I turned around.
Rosa, the woman from 4B, was walking toward me with a trash bag in one hand and her keys in the other.
“What happened?”
She glanced toward the stairwell, then lowered her voice.
“I don’t know if I should get involved, but your mother-in-law was here yesterday.”
I frowned.
“Carmen?”
“Yes.”
“What time?”
“Around four-thirty.”
That was strange already.
Yesterday had been Tuesday.
Javier and I had left home shortly after eight in the morning. He had gone to the office, while I had spent almost the entire day at an off-site work meeting.
We hadn’t come home until around seven.
“Are you sure it was her?”
Rosa looked at me as though the question were ridiculous.
“Elena, I’ve known your mother-in-law for five years.”
She had a point.
“Was she alone?”
That was when Rosa hesitated.
“No.”
The elevator doors opened behind me.
Neither of us stepped inside.
“Who was she with?”
“A woman.”
I felt a knot forming in my stomach.
“What woman?”
“I’d never seen her before. She looked about forty. Brunette, fairly tall. She was carrying a blue folder and a large handbag.”
I stared at her.
“Did they go into our apartment?”
Rosa nodded.
“Your mother-in-law opened the door with a key.”
My uneasiness immediately grew.
Carmen still had a copy of our apartment key.
We had given it to her two years earlier when Javier and I went away for ten days and needed someone to water the plants.
She had never returned it afterward.
I had mentioned several times that we should ask for it back.
Javier always said the same thing:
“She’s my mother, Elena. What’s she going to do?”
At that moment, the answer seemed to be: let strangers into our apartment while we weren’t home.
“How long were they inside?”
“I don’t know exactly. I left to do some shopping around quarter to five, and they were still there.”
“And when you came back?”
“They were gone.”
I fell silent.
Rosa watched me with concern.
“Maybe it’s nothing.”
“Maybe.”
But I was already pulling my phone out of my bag.
Three months earlier, we had installed a small security camera near the entrance.
It wasn’t inside our apartment.
It was in the hallway, pointed toward our front door, because several packages had disappeared from the building.
I opened the app.
Then I found the recording from the previous day.
4:27 p.m.
There was Carmen.
Red coat.
Black handbag.
Keys in her hand.
And beside her stood a woman I had never seen before.
Rosa had been right.
Tall.
Brunette.
Beige trousers, a green jacket, and a blue folder tucked under her arm.
Carmen unlocked our door.

But before they went inside, something happened that made me immediately turn up the volume.
The woman asked:
“Do the owners know we’re going inside?”
Carmen replied:
“My son does.”
I froze.
The woman asked again:
“And his wife?”
Carmen waved a hand dismissively.
“The apartment belongs to both of them. As long as Javier knows, that’s enough.”
My hands went cold.
I rewound a few seconds and listened again.
Exactly the same words.
Rosa was watching me.
“What is it?”
I didn’t answer.
I fast-forwarded the recording.
5:18 p.m.
The door opened again.
The unfamiliar woman came out first.
Then Carmen.
The woman was holding her phone and saying:
“I’ll send you the photos this afternoon.”
Carmen replied:
“Perfect. But send them to me first. I don’t want Elena seeing anything yet.”
My mouth went dry.
The recording ended.
I called Javier.
He answered on the third ring.
“Hi, honey. I’m about to go into a meeting. Is something wrong?”
“Yes.”
My voice must have sounded different, because his tone changed immediately.
“What happened?”
“Did you give your mother permission to enter our apartment with a woman yesterday?”
Silence.
“What?”
“I’ll ask again. Did you give Carmen permission to enter our apartment yesterday with a woman I don’t know?”
“No.”
He answered so quickly that I knew he wasn’t pretending.
“Are you sure?”
“Of course I’m sure. What are you talking about?”
I looked at my screen again.
“I have a recording.”
Another pause.
“What recording?”
“The hallway camera. Your mother went into our apartment around four-thirty with a woman. The woman asked whether the owners knew they were going inside. Carmen told her that you did.”
“Elena, I knew nothing about this.”
“That’s what I thought.”
“Who was the woman?”
“I don’t know. But when they came out, she said she’d send your mother some photos.”
Javier was silent for a few seconds.
“Photos of what?”
“Our apartment, I assume.”
“I’m coming home.”
“Don’t you have a meeting?”
“Not anymore.”
Forty minutes later, Javier arrived.
I was in the kitchen.
By then, I had watched the recording four times.
And I had noticed something else.
The woman had been carrying a laser measuring device.
I showed Javier.
His expression changed.
“That looks like something a real estate agent would use.”
I looked at him.
“Exactly what I thought.”
“But why would Mom bring a real estate agent into our apartment?”
I didn’t answer.
Because the idea running through my mind seemed too absurd.
Or at least I wanted to believe it was.
Javier called Carmen.
She answered immediately.
“Hi, son.”
“Mom, were you in our apartment yesterday?”
Silence.
“Yes.”
Javier closed his eyes for a moment.
“Why?”
“I needed to check something.”
“With whom?”
“An acquaintance.”
“What kind of acquaintance?”
“A woman who works in real estate.”
Javier looked at me.
I said nothing.
“Why did you bring a real estate agent into our apartment?”
“Don’t exaggerate. I just wanted her to see the place.”
“Why?”
Carmen sighed.
“Because I’m trying to help you.”
I leaned against the kitchen counter.
There it was.
Carmen’s favorite phrase right before she did something nobody had asked her to do.
“I’m trying to help you.”
Javier put the phone on speaker.
“Then explain.”
“Lucía and Andrés need a bigger apartment.”
I looked at Javier.
His sister Lucía lived with her husband in a two-bedroom apartment about fifteen minutes away from us.
“And what does that have to do with our apartment?” Javier asked.
“A lot.”
“Mom.”
“Your apartment is ninety-two square meters, has three bedrooms and a garage. You could sell it for a very good price right now.”
For a few seconds, I thought I had misheard her.
So did Javier.
“What did you just say?”
“That you could sell it.”
A short laugh escaped me.
Not because it was funny.
Because it was so absurd that my body couldn’t find another way to react.
Carmen continued:
“The agent thinks you could get around three hundred and twenty thousand euros for it.”
Javier stared at the phone.
“You had our apartment valued without asking us?”
“It wasn’t an official valuation.”
“You entered our apartment with a real estate agent.”
“Because if I had suggested it to you first, Elena would have said no.”
I raised my eyebrows.
At least she was right about that.
I stepped closer to the phone.
“Carmen, why exactly do you want us to sell our apartment?”
There was a brief silence.
“Because you could buy something smaller.”
“Excuse me?”
“Elena, you work from home three days a week. You don’t need three bedrooms.”
I looked toward the office door.
The third bedroom was precisely the room Javier and I both used as a home office.
“And what would happen to the money left over?” I asked.
Carmen took two seconds too long to answer.
“You could lend it to Lucía.”
I closed my eyes.
There it was.
The real reason.
“How much?”
“I don’t know exactly.”
“Carmen.”
“About fifty thousand euros.”
Javier let out a dry laugh.
“Fifty thousand euros?”
“You wouldn’t be giving it to her. It would be a loan.”
“Did Lucía ask you for this?” I asked.
Silence.
“Not exactly.”
“What does ‘not exactly’ mean?”
“She mentioned that the apartment they like is outside their budget.”
“That’s not the same as asking us for fifty thousand euros.”
“You’re family.”
Javier ran a hand over his face.
“Mom, have you spoken to Lucía about us selling our apartment?”
“Not yet.”
“So you organized all of this on your own.”
“Someone has to think of solutions.”
“To a problem nobody asked you to solve.”
Carmen’s tone changed.
“Javier, I don’t understand why you’re reacting like this. The apartment belongs to you too.”
I looked at my husband.
He looked at me.
We had bought the apartment together four years earlier.
Both our names were on the deed.
We had both contributed to the down payment.
We both paid the mortgage.
“Exactly,” Javier replied. “It’s ours. Not yours.”
“I’m your mother.”
“That doesn’t give you the right to enter our home when we’re not there and show it to strangers.”
“I had a key.”
“For emergencies.”
“You never said that.”
This time, I interrupted.
“Carmen, what did you think we gave you that key for?”
“So I could get in whenever necessary.”
“And what emergency was there yesterday?”
She didn’t answer.
“A possible sale we didn’t even know existed?”
“I just wanted to know how much the apartment was worth.”
“Then you could have asked us.”
“I already knew what you were going to say.”
“Exactly. No.”
Silence.
Javier picked up the phone.
“Mom, I need you to give us our key back.”
“What?”
“Our apartment key.”
“Don’t be ridiculous.”
“I’m not being ridiculous.”
“After everything I do for you, you’re taking the key away from me?”
“After you entered our home without permission with a stranger, yes.”
Carmen fell silent.
Then she said:
“Elena is turning you against me.”
I watched Javier’s expression harden.
“No. You entered my home without telling me and lied by saying I knew about it.”
“I was only trying to—”
“Help us. Yes, you already said that.”
He took a deep breath.
“Bring the key over this afternoon.”
“I’m not driving all the way there just because of a key.”
“Then we’ll come and get it.”
He hung up.
I looked at him.
“We can change the lock.”
“We’re doing that anyway.”
At six that evening, we went to Carmen’s house.
Antonio opened the door.
When he saw our faces, he frowned.
“What happened?”
From the living room, Carmen shouted:
“Nothing. They’re making a huge drama out of something trivial.”
Antonio looked at us.
“What something trivial?”
Javier stepped inside.
“Mom brought a real estate agent into our apartment yesterday while we weren’t home.”
Antonio blinked.
“What?”
Carmen appeared in the hallway.
“It wasn’t because I wanted to sell it.”
“Then why?” I asked.
“To find out what it might be worth if you ever decided to sell.”
Antonio looked at her.
“And why do you need to know that?”
“Because Lucía needs help.”
It took Antonio a second to understand.
Then he closed his eyes.
“Carmen…”
“What?”
“Not again.”
That immediately caught my attention.
“Again?”
Carmen shot him a furious look.
“Antonio.”
But he was clearly tired of it.
“Two weeks ago, she called a car dealership and asked how much they would pay for your car.”
Javier froze.
“Which car?”
Antonio looked at me.
“Elena’s.”
Slowly, I turned my head toward Carmen.
“You tried to have my car valued?”
“I only asked.”
“Why?”
Carmen pressed her lips together.
I answered for her.
“To help Lucía.”
Antonio nodded.
“She said that since Elena works from home several days a week, maybe you could manage with just one car.”
I couldn’t help it.
I laughed.
“Impressive.”
Carmen crossed her arms.
“What’s wrong with thinking about family?”
“Nothing,” I replied. “The strange thing is that you always want to help the family with our things.”
Antonio lowered his eyes to hide a smile.
Carmen turned toward him.
“You think this is funny too?”
“No. I think Elena has a point.”
“Of course. Now everyone is against me.”
Javier held out his hand.
“The key.”
Carmen didn’t move.
“Javier.”
“Mom. The key.”
“I’m your mother.”
“And that is our home.”
They stared at each other for several seconds.
Finally, Carmen opened a drawer in the cabinet by the entrance.
She took out a key.
Then she placed it in Javier’s palm.
“I hope you’re happy now.”
Javier looked at her.
“No. I’m disappointed.”
That silenced her.
We left ten minutes later.
The next morning, I called a locksmith.
Even though Carmen had returned the key, neither of us knew whether she had made any copies.
By eleven-thirty, we had a new lock.
That same afternoon, something happened that I hadn’t expected.
Lucía called me.
“Elena, what’s going on?”
“Didn’t your mother tell you?”
“She said you were angry because she tried to help us with the apartment.”
I sighed.
“Lucía, your mother entered our apartment with a real estate agent to find out how much we could get for it if we sold it.”
Silence.
“What?”
“Her plan was for us to buy something smaller and lend you around fifty thousand euros.”
“Fifty thousand euros?”
“Yes.”
“I never asked her for that.”
“I know.”
Lucía was silent for a few seconds.
“Andrés and I looked at an apartment last week. I told Mom we loved it, but we’d rather wait another six to eight months and save more money.”
“That’s what I thought.”
“Oh my God.”
“There’s more.”
“More?”
“She also asked how much someone might pay for my car.”
Lucía made a sound somewhere between a laugh and a groan.
“You’re kidding.”
“Antonio told us.”
“I’m calling her.”
“Lucía…”
“No. This affects me too now. She’s using my name to justify things I never asked her to do.”
An hour later, Javier received a message from his mother.
It said only:
“I hope you’re satisfied. Now Lucía is angry with me too.”
Javier showed me the screen.
“Should I answer?”
“If you want.”
He thought for a moment.
Then he typed:
“We’re not satisfied. We just want you to respect our decisions and our home.”
There was no reply.
Almost three weeks passed before Carmen visited us again.
This time, she rang the doorbell.
I opened the door.
She looked at the lock.
Then at me.
“You changed the lock?”
“Yes.”
“Even though I returned the key?”
“Yes.”
She pressed her lips together.
“You don’t trust me.”
I looked at her for a few seconds.
“Carmen, the trust didn’t disappear when we changed the lock.”
I paused.
“It disappeared when you used the key.”
She didn’t answer.
From the living room, Javier called out:
“Who is it?”
Carmen raised her voice slightly.
“Me.”
“Come in, Mom.”
She stood still for a second.
Waiting.
Then I understood what she was waiting for.
I stepped aside.
“You can come in.”
She entered.
Maybe it seemed like a small, insignificant detail.
But it wasn’t.
For the first time in years, Carmen had been forced to ring the doorbell to enter our home.
And wait for someone to let her in.
The following week, Rosa stopped me by the elevator again.
“Elena.”
I smiled.
“What happened this time?”
She looked at our door, then at me.
“Nothing.”
She gave me a thumbs-up.
“I just wanted to tell you that your mother-in-law came by yesterday. She rang the bell and waited outside.”
I laughed.
“Perfect.”
The elevator doors opened.
This time, I stepped inside.
And as the elevator carried me down to the ground floor, I thought about how sometimes it takes years to establish a boundary.
And other times, all it takes is an observant neighbor, a security camera, and a mother-in-law who forgets that having a key doesn’t mean you own the door.
