Why do the general and his wife like amir so much?

Amir and Soraya's traditional courtship creates a little Afghan oasis in the confusion of America, which Baba and the Taheris greatly appreciate. As immigrants, even "former ambassadors, out-of-work surgeons, and university professors" are reduced to selling used goods at the flea market. Baba is a gas station worker and General Taheri a welfare recipient, in the matter of their children's courtship they feel like important Afghan men again.
