What story does Garbes tell to show how her mother is a natural-born caretaker?

Garbes describes her mother as a natural-born caretaker. She describes how her mother grew up in Mandaluyong, a city that makes up Manila, and she found a frail chick in the courtyard of her family's home. The bird was small, bedraggled, and it had trouble walking. She decided to nurse it back to health. She fed it, stroked it, and tucked it into her bed at night. The bird recovered, and she decided to keep it as a pet. One morning she awoke to find it dead. She had rolled over and suffocated the bird in her sleep.
