After Ami's Birthday, Amir blames hassan for stealing, and when asked about it, Hassan said he did it. However Baba tried to stop it, Ali said " we are leaving Agha sahib"(Hosseini 106). This event shows how much Baba cares for Hassan, because he forgave him for Babas most hated mistake, stealing. Also this shows the cowardness of Amir and his Jealousy. He couldnt stand Hassan being loved by Baba, so he lets him leave without fessing up. This is also an additional example of Hassans devotion.
