“[H]e didn’t know what kept him and Tony together except that, after Tony, other kids seemed boring.” 

The deep bond Joel and Tony have forged over the years despite their contrasts shows how important they are to each other even though they argue. By providing insight into Joel’s feelings toward Tony, the author shows why Joel values his friendship with Tony even when he is frustrated by him. Joel sees Tony as rare and unique.

“Seeing his father and the firm grip he maintained on Bobby’s hand gave Joel an idea. He would ask for permission to ride his bike out to Starved Rock. He wouldn’t mention about the bluffs, of course. He wouldn’t have to. His father was sure to say that the ride to the park was too far, too dangerous.” 

Joel doesn’t want to tell Tony “no” because he doesn’t want to seem childish and afraid. He decides to ask his father if they can go to the park because he is sure that his father will not give them permission. Rather than being honest, he attempts to manipulate the situation by lying to both Tony and his dad. This is Joel’s first dishonorable action.

“Joel’s father didn’t take his eyes off of Joel’s face. ‘On your honor?’ he said. ‘You’ll watch for traffic, and you won’t go anywhere except the park? You’ll be careful the whole way? ‘On my honor,’ Joel repeated, and he crossed his heart, solemnly, then raised his right hand.”

The promise that Joel makes to his father at the beginning of the book frames the entire narrative. The significance of the title is established in this moment of trust between a father and son. Joel’s breakdown over his lies and his grief teaches him what honor means.
