A poor student accepted a job cleaning the house of an elderly woman who lived alone in a small alley. When he saw that she was sick and could barely walk, the young man not only did the work he was paid for, but also cooked for her, went to the market, and took her to the hospital whenever she felt unwell. For many months, the elderly woman never paid him the money she had promised. But before she died, she left a single letter that left him in shock. My name is Diego. I’m 21 years old and a third-year student at a university in Guadalajara. To pay for my studies and daily expenses, I take all kinds of part-time jobs—from giving private lessons to helping out at a café. One day, in a Facebook group where people post job offers, I found an ad looking for someone to clean the house of Doña Carmen, an elderly woman who lived alone in a small alley near the city center. The first time I went to her house, I was struck by how fragile she looked. Doña Carmen was very thin, with completely white hair and trembling hands resting on a cane. Her house was a small old home filled with worn objects: a radio that no longer worked, several faded photographs hanging on the wall, and a wooden bed worn down by the years. She told me she suffered from rheumatism and high blood pressure, and that it was very difficult for her to walk, which was why she needed someone to clean the house once a week. The job was simple: sweep, dust, and wash a few dishes. She promised to pay me 200 pesos for each visit. For a student like me, that money meant a lot. During the following visits, I began to notice how difficult her life really was. The refrigerator was almost always empty—just a few eggs and a bunch of wilted vegetables. Many times her meal was simply rice with a little sauce. When I asked her why she lived like that, she told me her children lived far away and that she didn’t want to bother them. I felt very sorry for her. So after finishing the cleaning, I started staying a little longer to go to the market, buy some meat or fish, and cook her a proper meal. Doña Carmen loved it when I cooked. Her eyes would light up every time she tasted the hot broth I made for her. Sometimes, when the pain in her joints became too strong, I would take her to the public hospital myself and patiently wait until they gave her medication. One time, while we were leaving the hospital, she took my hand and said in a soft voice.

She never spoke badly of them.

That impressed me.

She would only say,

“A mother never stops being a mother, even when her children forget how to be children.”

One day I found, in a half-closed drawer, several old letters returned by the mail.

All addressed to the same place in Monterrey.

All with the same last name.
None opened.

I said nothing.

Neither did she.

But that night, for the first time, when I was leaving, she asked,

“Could you come back tomorrow?”

I did.

And the next day as well.

Her health began to worsen quickly.

She could hardly get up by herself.

Her breathing came in small, struggling efforts.

One morning the doctor at the community clinic pulled me aside and told me bluntly,

“She’s very weak. I don’t think she has much time left.”

That afternoon, leaving the clinic, I helped her slowly into a taxi. Doña Carmen stayed quiet, looking out the window as if she were seeing a city that no longer belonged to her.

Before getting out in front of her house, she said,

“Diego… when I die, don’t let them throw away my things without checking the wardrobe.”

I felt a blow in my chest.

“Don’t say that.”

“Promise me.”

That word again.

And again, I nodded.

The last two weeks were very hard.

She could hardly eat anything.

I moistened her lips with water.

I tucked in her blankets.

I read newspaper headlines out loud so she could feel that the world was still entering through her door.

One night she grabbed my wrist with a strength I didn’t know she still had.
