From The Kite Runner
[explaining Sohrab's presence
] You see, General Sahib, my father slept with his servant's wife, and she bore him a son named Hassan. Hassan is dead now. That boy sleeping in the other room is Hassan's son. He's my nephew. That's what you tell people when they ask. And one more thing, General Sahib: you will never again refer to him as "a Hazara boy" in my presence. He has a name, and it's Sohrab.
