After his friendship with Josie deteriorates, Peter befriends Derek, often creating video games with him. Peter's home life is rocky; he never seemed to relate to his parents, despite his mother's best efforts. His older brother, Joey, teased Peter and often encouraged bullying, even fabricating that Peter was adopted. During his high school years, Peter realizes he is in love with Josie, sparking a drastic chain of events. Peter emails Josie a love letter, which is intercepted by some of Josie's popular friends.

alienation. Josie deeply dislikes her friends' and boyfriend's treatment of less popular students, but is never able to stand up to them.
