How has Amir's childhood home changed since he last saw it? By what change do you think he is most affected? why?

Farid drives Amir to Baba’s house. It is falling apart, but recognizable. Amir finds his bedroom window and remembers looking out of it to watch Ali and Hassan the morning they left. He goes up the hill to the pomegranate tree where he and Hassan used to play, but Farid tells him they should leave.
