Amir, a well-to-do Pashtun boy, and Hassan, a Hazara boy who is the son of Ali, Amir's father's servant, spend their days kite fighting in the hitherto peaceful city of Kabul. Flying kites was a way to escape the horrific reality the two boys were living in. Hassan is a successful "kite runner" for Amir; he knows where the kite will land without watching it. Both boys are motherless: Amir's mother died in childbirth, while Hassan's mother, Sanaubar, simply abandoned him and Ali. Amir's father, a wealthy merchant Amir affectionately refers to as Baba, loves both boys. He makes a point of buying Hassan exactly the same things as Amir, to Amir's annoyance. He even pays to have Hassan's cleft lip surgically corrected. On the other hand, Baba is often critical of Amir, considering him weak and lacking in courage, even threatening to physically punish him when he complains about Hassan. Amir finds a kinder fatherly figure in Rahim Khan, Baba's closest friend, who understands him and supports his interest in writing, whereas Baba considers that interest to be worthy only of females. In a rare moment, when Amir is sitting on Baba's lap rather than being shooed away as a bother, he asks why his father drinks alcohol, which is forbidden by Islam. Baba tells him that the Mullahs are hypocrites and the only real sin is theft which takes many forms, the worst being having an affair.
