This shows that they are really good friends because George has agreed to tell Lennie for the millionth time about how they're going to get that piece of land.
Guys like us, that work on ranches, are the loneliest guys in the world. They got no family....
This shows that through Slim's eyes, it's pretty rare to see two people traveling together. This goes to show how huge their friendship is, and how something like this is very precious.
Hardly none of the guys ever travel together. I hardly never seen two guys travel together.
This is the part where George was about to shoot Lennie. He doesn't want to, but he has no other choice. And before he does, he wants Lennie to know that he wasn't mad at him. This is where George has to let him go, and it is hard for him, but he has to do it.
No, Lennie. I ain't mad. I never been made an' I ain't now. That's a thing I want ya to know.
