Rebecca is a teenage girl and a recent high school graduate. Rebecca lives with her grandmother, or her "Oomie", as Rebecca calls her. Rebecca is Enid Coleslaw's best friend, although they frequently argue with each other and Enid frequently tells Rebecca what to do. Like Enid, Rebecca spends most of her time making fun of other people. Although Enid is convinced that boys find Rebecca more attractive than her, Rebecca is equally convinced that almost every boy likes Enid more than her. Near the end of the story, Enid tells Rebecca that Josh is more attracted to Rebecca than Enid, which causes Rebecca to pursue Josh romantically and begin a relationship with him.
