What does Amir mean when he tells Farid that he does not “want to forget anymore” as he leaves to climb the hill that he and Hassan had climbed as children (263)? What are the implications of this statement for Amir?

Amir is tired of running from his memory. The shame of not helping Hassan in on that fateful day burns in his soul. When he returns to Afghanistan, it is with purpose. He refuses to keep trying to forget: he needs to atone for his sin.
