The story jumps back in time to 1933, the year Baba is born and Zahir Shah becomes king of Afghanistan. Around the same time, two young men who are driving while drunk and high hit and kill Ali’s parents. Amir’s grandfather takes the young Ali in, and Ali and Baba grow up together. Baba, however, never calls Ali his friend. Similarly, because of their ethnic and religious differences, Amir says as a child he never thought of Hassan as a friend. Even so, Amir’s youth seems to him like a long stretch of playing games with Hassan. But while Amir would wake up in the morning and go to school, Hassan would clean the house and get groceries. Amir often read to Hassan, who was illiterate. Their favorite story was “Rostam and Sohrab,” in which Rostam fatally wounds Sohrab in battle and then finds out Sohrab is his lost son.
During one reading session under their favorite pomegranate tree, Amir begins to make up his own story while he is reading to Hassan. Hassan says it is one of the best stories Amir has read. That night, Amir writes his first short story, about a man whose tears turn to pearls. The man finds new ways to make himself sad so he can cry and become richer, until the story ends with him sitting atop a mound of pearls, sobbing over the wife he has stabbed. Amir tries to show Baba the story while Baba is speaking with Rahim Khan, but Baba does not pay much attention. Rahim Khan takes the story instead. When Rahim Khan leaves later than night, he gives Amir a note. In the note, he tells Amir he has a great talent. Amir goes to where Hassan sleeps and wakes him so he can read him the story. When Amir has finished, Hassan tells him the story is terrific. He has only one question: why didn’t the man make himself cry with onions? Amir is annoyed he didn’t think of it himself and has a nasty thought about Hassan being a Hazara, though he says nothing.
One night, gunfire erupts in the street. Ali, Hassan, and Amir hide in the house until morning. Amir says that night was the beginning of the end of the Afghanistan they knew. It slipped away further in 1978 with the communist takeover, and it disappeared completely in 1979 when Russia invaded. The gunshots were part of a coup in which Daoud Khan, the king’s cousin, took over the government. Because the roads are closed that night, Baba doesn’t arrive home till dawn. That morning, Amir and Hassan hear talk of what happened on the radio, but they don’t understand what it means that Afghanistan has become a republic. They decide to go climb a tree.
While they’re walking, a rock hits Hassan. Amir and Hassan discover Assef and two other boys from the neighborhood. Assef is a notorious bully. He is one of the children who mocks Ali’s limp and calls him names. He also carries a set of brass knuckles. Assef calls Hassan a flat-nose and asks if they heard about the new republic. He says his father knows Daoud Khan, and that next time Daoud Khan is over for dinner he’s going to talk to him about Hitler. Hitler had the right idea about ethnic purity. Afghanistan is the land of Pashtuns and the Hazaras just pollute the country. Assef takes out his brass knuckles. He says Amir is part of the problem for being friends with a Hazara. For a moment, Amir thinks that Hassan is his servant, not his friend, but he quickly recognizes his thought is wrong. As Assef goes to hit Amir, Assef suddenly freezes because Hassan has his slingshot aimed at him, which allows Amir and Hassan to get away.
After Daoud Khan’s coup, life goes back to normal. The following winter, on Hassan’s birthday, Ali calls Hassan inside. Baba is waiting for him with a man named Dr. Kumar. Dr. Kumar is a plastic surgeon. He is Hassan’s present. Dr. Kumar explains that his job is to fix things on people, sometimes people’s faces. Hassan touches his lip in recognition. The surgery works, and though Hassan’s lip is raw and swollen while he recovers, he smiles all the while. The winter after, all that remains of his cleft lip is a faint scar.
The relationship between ordinary people, such as Hassan and Amir, and political events like Daoud Khan’s coup are a main focus of this section. At the beginning of this section, for instance, Amir says in his narration that Baba was born in 1933, the same year Zahir Shah became king. Why does Hosseini set up this parallel? Because the fates of Zahir Shah and Baba—as well as the fates of those dependent on Baba like Amir, Hassan, and Ali—are all bound together in a sense. When Daoud Khan, in a bloodless coup, takes over in Chapter 5, we know that the lives of our characters are about to change, even if we aren’t sure how. Amir’s and Hassan’s encounter with the racist boy Assef is a hint: the change is not going to be for the better. The rules that govern life in Kabul have been stirred up, and power balances have shifted. Bloodshed and violence may be in store. We witness this from the perspective of Amir, a young boy who does not know what it means that Afghanistan has become a republic. What he does know is this bully, Assef, suddenly has more power because of who his father knows. Amir feels uncertain and threatened, as many Afghans likely did.
