The summer after high school is often a time of trying to figure out one's place in the world. Porcellino portrays his adolescent-on-the-brink-of-adulthood self trying to find a balance between getting to know himself as an individual and finding a way to feel less isolated. This book also manages perfectly capture avoidance as a way of dealing with the realization that you've attained a major milestone in life without a clue about what comes next for you. Sometimes the teenage John seems to be working hard at staying a kid, doing kid things with his friends, and other times, confronted by those same friends with the need to make decisions about college and adulthood, he sinks into depression. The words, "I don't know" appear over and over throughout the story, and John is often completely paralyzed with indecision, even about small things such as whether or not it's ok to try to hold the hand of a girl he likes.
