I do think that both vignettes had an enough writing about Marin and Alicia's identity. The main character, Esperanza analyze who they are and actions they attend to do. For example, in the vignette "Marin. she explained about her boyfriends and how she want is going to get marry after she gets a job. Esperanza explained how she respect Marin because she is older and mature in a diversity of ways and she doesn't get frighten as much as herself. "Alicia Who Sees Mice" also identified Alicia's identity and she wrote how she studies hard every night until she sees mice and because Alicia wants to get to College, she studies hard no matter what.
