The House on Mango Street by Sandra Cisneros

Esperanza takes her first job at Peter Pan Photo Finishers. While the job is simple, Esperanza struggles with her shyness throughout her first day on the job. She feels better at the end of the day, when she meets a kind "Oriental man" who tells her they can be friends and sit together at lunch. Esperanza's trusting nature betrays her however, when the man takes advantage of the innocent birthday kiss to her cheek.
