Hassan better understands the relationship and social standing between the two boys than does Amir. Hassan recognizes his position as the son of the household servant, Ali. Though Ali and Hassan are treated with great kindness by Baba (and we find out later in the book one of the reasons why), they do not live in the family home; instead, they reside in a mud hut on the property. Both Hassan and Ali are reminded regularly by others of their lower-class Hazara ethnicity, so they have no illusions about their place in Baba's home or in society. Hassan loves Amir for a variety of reasons: He is proud to be a friend to the son of a man with such power and wealth as Baba; he appreciates the time that Amir spends with him; he enjoys the stories that Amir reads to him; and for Hassan, Amir is his closest friend. Because he is a servant's son, Hassan has an innate sense of service, another reason he is always willing to run Amir's kite.
