What are the motifs in The Kite Runner by Khaled Hosseini?

Devotion and friendship are recurring ideas. Amir, Hassan, Baba, Ali, and Sohrab are all examples of this theme but each relationship has different levels of devotion. Amir and Hassan grow up together, and they are devoted to each other but not in the traditional manner. Amir depends heavily on Hassan for companionship, but he is also jealous of him, especially Hassan’s relationship with Baba. Amir admits that he and Hassan aren’t friends. He says he plays with Hassan when there’s no other option. Hassan, however, is completely devoted to Amir and depends entirely on him for friendship and companionship. Ali is also completely devoted to Baba but that devotion is based on the servant-master relationship rather than friendship.
