The narrator first meets Doña Carmen while helping her in an informal caregiving arrangement during their student years. Initially motivated by a modest payment, the narrator quickly forms a bond with her as they witness her frailty, isolation, and quiet endurance of pain. Doña Carmen, despite her poverty and estranged children, insists on the narrator continuing visits even if she cannot pay, revealing her deep need for companionship and human connection in her final months.

Over time, their routine evolves from transactional to deeply personal. The narrator learns Doña Carmen’s habits, stories, and silences, while also observing her declining health. She shares fragments of her life, expressing love and lingering grief for her deceased son, Tomás, and quietly acknowledging the distance of her living children. Their visits become a form of mutual care and understanding, transcending money or obligation.

In her final days, Doña Carmen expresses guilt for not being able to pay the narrator, highlighting how she sees the visits as a debt of gratitude rather than mere care. After her death, the narrator discovers a letter and a key she left behind, revealing a hidden box containing savings, the deed to her house, and memories of her late son. She had chosen to leave her estate to the narrator, recognizing that they had provided the consistent presence and dignity her own children failed to offer.

The narrator uses the inheritance to rebuild their life while cherishing the deeper lessons learned: the value of quiet consistency, the dignity in caring for others, and the meaningful impact of presence. Even years later, rituals like making chicken broth in her memory serve as a reminder of the profound influence she had on shaping their character and perspective on life.
