In the winter of 1975 Hassam and Amir won the kite tournament in Kabul. This was the closest they would ever be and just a few minutes later they would begin to be torn apart by the violence of Assef against Hassam. When Amir wins the tournament, Hassam tells him that he will run the kite for him. Amir tells him to bring the kite back to him. Hassan, "cupped his hands around his mouth and yelled, " For you, a thousand times over." Now years later and thousands of miles away in California Amir cuts a kite and turns to Sohrab, Hassan's son, and asks,
"Do you want me to run that kite for you?" I thought I saw hin nod. "For you a thousand times over, " I heard myself say. Then I turned and ran.
This scene is significant because Amir's life has now come full circle. He is now running the kite, not just for Sohrab, but for Hassam, and for himself and the history that they shared.
The ending is significant because Amir and Sohrab are flying kites. Once Amir and Sohrab defeat a kite, Amir tells Sohrab that he will run the kite for him, just as Hassan (Sohrab's biological father and Amir's half brother) had done for him.
