Step-by-step explanation:
The short story "Eleven" by Sandra Cisneros was published in 1991. It is is a story about the birthday of a young girl Rachel. It begins with the girl's thoughts about the contemplation of aging and birthdays. Then the day becomes worse during a day at school, as her teacher, Mrs. Price, forces her into a humiliating social predicament by making her wear an ugly red sweater that isn't hers.
Sandra Cisneros decided to write this story from the first point of view because it helps to reveal the thoughts, feelings, and emotions of a narrator. In our case, we can better understand Rachel, her experience of the birthday, what she felt at school, how it affected her. This point of view helps to become closer to Rachel, to sympathize with her, to feel what she feels in the narration, to live through her experience.
