Besides the obvious tradition of kite flying/running, Hosseini presents many Afghan traditions. Through the relationship of Amir and Hassan, he portrays the Afghans' tradition of ethnic prejudice. Amir represents the Pashtuns, the highest ethnic group, and Hassan represents the Hassans, the servile group.
Other Afghan traditions featured that say much about Afghanistan's rich culture are the engagement process. Baba must approach General Taheri for his daughter's hand. At Amir and Soraya's wedding, they gaze at one another in a mirror under a veil.
While Hosseini is trying to give his reader a better understanding of Afghan culture by incorporating these traditions, he also uses them to advance his themes of redemption, relationships, and parental approval.
