Thank you for the opportunity to help you with your question!
(A)it seems like Amir leads a relatively charmed life. He's got a great
friend in Hassan, his father is wealthy, he adores his father, etc. There's jealousy and some cruelty
and power struggles. But there's also adoration, loyalty, and genuine
affection between the boys.
OK – on to more pain and suffering.
Most of the early conflict seems confined to the lives of Ali and
Hassan. There's racial discrimination toward them, Sanaubar leaving,
Hassan's harelip, and the soldiers' taunting of Hassan
(B)No he just came up with a story echoed to touch many peoples lives
