Arnold's main friend – and only friend – on the reservation in Wellpinit is Rowdy. Once he moves to Reardan, though, he becomes friends with a whole host of people: Penelope, Gordy, Roger, even the school basketball coach. Why is it important that Arnold meet new people and make new friends? What does he learn from these people? Why is it important that he reconcile with Rowdy in the end of The Absolutely True Diary of a Part-Time Indian?
Connecting with different people and making new friends is an important part of finding out who we really are.
Relying too heavily upon the strength and friendship of another person can prevent us from ever learning how to stand up for ourselves.
