Answer:
In the book "The Kite Runner" by Khaled Hosseini, Amir harbors some resentment towards his father Baba due to their strained relationship and Amir's sense of inadequacy in Baba's eyes.
One reason for Amir's resentment towards Baba is that he feels neglected by his father, who is often too busy with his work and social obligations to spend time with him. Baba also shows more affection towards Hassan, Amir's childhood friend and servant, which makes Amir jealous and resentful.
Another reason for Amir's resentment towards Baba is that he feels that his father does not understand or appreciate him. Baba values physical strength, bravery, and athleticism, while Amir is more introverted and bookish. Amir feels that he cannot live up to his father's expectations and that he is a disappointment to him.
Amir lies to his father and says that Hassan is too sick to come with them on their outing to watch the Buzkashi tournament because he is ashamed of his friendship with Hassan. Amir witnesses Hassan being sexually assaulted by Assef, a bully, but does nothing to stop it, and feels guilty and ashamed for his inaction. He is afraid that if he brings Hassan with them, he will be reminded of his guilt and his father will find out what happened.
Baba is a complex character in the novel. On the one hand, he is a strong and charismatic leader who is respected by his community for his bravery, generosity, and honesty. He is also a successful businessman who has built a fortune from scratch. On the other hand, he is flawed and imperfect, with a tendency towards anger and impatience. He is also somewhat hypocritical, as he values loyalty and honor but has kept a secret about his own past from his son. Ultimately, Baba is a man who is both admirable and flawed, much like any human being.
