Amir and Baba have dramatically different experiences in America, and their relationship develops as they spend more time together. Immigrating to America gives Amir a second chance at life and is a place where he can move on from his traumatic past and start fresh. Unlike Baba, Amir thrives in America because he can speak the language fluently and excels in the classroom. Amir's experience in America occupies his mind, and he transforms into a confident young man. Amir eventually graduates from high school and follows his dream of becoming a writer by enrolling in college to earning an English degree.

Baba sacrifices everything when he moves to America and struggles to assimilate into the foreign culture. Baba lost his business and wealth when he moved to America and works long hours at a local service station to provide for himself and Amir. Baba also finds it difficult to speak English and gets into a heated altercation with a local merchant when he requests his I.D. to accept a check. As a former business owner renowned in his hometown of Kabul, Baba is significantly humbled by his experience in America.

Despite Baba's losses and negative experiences, his relationship with Amir significantly improves. Baba and Amir rely on each other and enjoy spending their Saturdays together at the flea market. Baba becomes more accepting of Amir and expresses his gratitude towards him, which enhances Amir's self-esteem. Amir also learns to appreciate Baba's sacrifices and is thankful that he gave him a second chance at life. The experience in America influences Baba to develop into a more compassionate, accepting father and allows Amir to grow as an individual.
