What is the main conflict in The Last of the Menu Girls by Denise Chavez?

In a semi-autobiographical series of short vignettes, author Denise Chavez captures the life of a typical Hispanic-American teen, searching, as are all adolescents, for purpose, self-identity, and adulthood. Rocio Esquibel is an ordinary girl, living on an ordinary street, in an ordinary town in southern New Mexico.
