Because she denies Heidi's repeated gestures, she is left by herself to imagine what life would be like if she were able to let her guard down and be more like her friend Heidi. Dina's journey can be described as full circle, where she begins as a socially isolated individual, turns into an individual who is able to acknowledge and accept a community, then she rejects the relationship and ends the journey in the same spot as she began, gaining nothing along the way besides a desire to change.
Dina starts the story as a guarded and isolated individual who is close-minded about interacting with other people. When she is at orientation with the people that she would be starting a residential community with at Yale, she doesn't play the trust fall game there is "no way" she would partake in that activity (117). This is because she has no intention of getting to know any of the people at the university, much less establishing trust and a relationship with them. She displays an inability to trust people, but more importantly the unwillingness to try. This is a trait that has defined Dina since she was young; she remains guarded and closed off to prevent others from forming any opinions about her, whether good or bad. Growing up in a less privileged area in Baltimore, when Dina had to go to the grocery store she would go out of her way to prevent judgment, she even says, "I hated those cashiers, and I hated them seeing me with food stamps, so I took the bus and shopped elsewhere." (132) In addition to growing up in a lower income family, Dina was forced to guard herself, because she "was an honor roll student" (118). Dina deeply fears rejection and avoids it at all costs. If any situation occurs that makes her feel uncomfortable, unaccepted, or different from others, then she shuts down. She goes entirely out of her way to ensure there is little to no chance of her receiving judgment and also to be sure that she is able to remain socially isolated in the community of one.
