The main theme is about Shawn's quality of life. With his handicap, Shawn will never be able to have a relationship with a woman. He'll never be able to walk, feed himself, or even take care of himself on his own. He will never be able to hold a job to take care of himself. These are things to consider, and the end of the story makes the reader wonder if his life is worth keeping and living. Hopefully most of us say YES! Shawn wants to live. He has no desire to leave this world yet. He's got a great sense of humor, has a great memory, and is quite intelligent. All of these traits play into whether his life is worth living. Others may see his life as unbearable, but to Shawn, it's what he knows. It's his life to live. No one else knows what goes on in his mind, so they don't know that he's content.
