I have two: I really appreciated the truth of Baba's remark to Amir at the end of Chapter 11 when he says, "'It may be unfair, but what happens in a few days, sometimes even a single day, can change the course of a whole lifetime, Amir.'" Baba is speaking about Soraya's past mistakes, and Amir is obviously going to be reminded of his past mistake with Hassan, but what I like about the quote is that is such a clear statement of the theme of the novel and it is SO true for all of us.
My other favorite quote is the last page. While it could be considered a let down that Sohrab shows so little improvement upon his safe arrival in the US and his being in the loving environment of Amir's home, I think it is actually more poignant and significant that Amir is really going to have work hard to atone for the past. Sohrab's tiny smile is kind of heart-breaking, and yet makes the reader smile at the same time. From Amir's perspective:
Only a smile . . But I'll take it. With open arms. Because when spring comes, it melts the snow one flake at a time, and maybe I just witnessed the first flake melting.
To me it is a very appropriate ending to the novel. The short phrases each on their own line and the metaphor at the end work very well together.
Mine is either Baba's "sin" theory in Chapter 3 or Rahim Khan's admonishment to Amir that "there is a way to be good again" (found in the opening chapter and again when the novel catches up to present day). I like Baba's theory because it is intriguing to discuss with others, and I appreciate Rahim Khan's statement because it presents one of the book's central themes: redemption.
Mine was : " A boy who can't stand up for himslef, becomes a man who can't stand up to anything".
That was Baba's, I honestly think it's true though I didn't like Baba's character in the novel.
