"Well--look, we're gonna work on a ranch like the one we come from up north."
Chapter II - Learning
"He's a nice guy."
"What kind of guy is the boss?"
Chapter III - Human Kindness
"When his aunt Clara died, Lennie just came along with me outworkin. Got kinda used to each other, after a little while."
This quote is under the theme hope because it's what they want to do. There wish is to work on a ranch like one from weed. They hope to buy their land
Chapter IV - Discrimination
"Cause i'm black. They play cards in there, but I can't play because i'm black."
There are many questions that George has, but here's one of them. He's asking about the boss and Candy tells him that he's a nice guy. George is trying to settle in.
Chapter V - Grief
"Why do you got to get killed."
"For the rabbits."
I think this relates to human kindness because they became good friends after a while. This must have made Lennie feel better because he had someone to talk to.
Chapter VI - Dreams
This quote refers to the theme racism because they treat him like a slave. He really doesn't have much rights at ranch and no one really cares about him.
"why ain't you wanted."
Lennie is in grief because he didn't mean to kill his own pup. He blames himself and tries to hide the dead pup.
Lennie dreams to have a land with George so he can tend the rabbits. Sadly it won't happen because George has murder on his mind.
