I always thought that the whole story (Eskimos) was about people trying to reach out to other people, find some human connection. the sandwich is Selena's brother's attempt to form a human bond with Ginnie, some person he just met, but he's too far gone, too desperate, he's been alone too long. However, seeing this DOES change her feelings about Selena, and she goes on to try to form a bond with her instead, ergo the movie date later on. just an idea, -steve
