A poor student once took a small job cleaning the house of an elderly woman who lived alone in a narrow alley.

She was frail and barely able to walk. Seeing her struggle, the young man didn’t just do the work he was paid for. He began cooking for her, going to the market, and even taking her to the hospital whenever her health worsened.

Months passed.

Yet the old woman never paid him the money she had promised.

Then one day she died… leaving behind a single letter that would change his life forever.

My name is Diego.

I’m twenty-one years old and a third-year student at a university in Guadalajara.

To cover tuition and everyday expenses, I take any job I can find—tutoring, working in a cafeteria, helping people clean their homes.

That’s how I first met Doña Carmen.

When I arrived at her house for the first time, I was shocked by how fragile she looked.

She was extremely thin. Her hair was completely white, and her hands trembled as they rested on a wooden cane.

Her house was small and worn by time.

Inside were objects that looked as if they belonged to another era: a broken radio, faded photographs hanging on the walls, and a wooden bed whose surface had been worn smooth over the years.

She explained that she suffered from rheumatism and high blood pressure, which made it difficult for her to move around.

All she needed was someone to clean the house once a week.
