The character I’m focusing on is crooks.
A key quotation that sums up crooks is “cause I’m black, they play cards in there but I can’t play because I’m black. They say I stink. Well, I tell you, you all stink to me.” From what crook just said to Lennie you can see that he knows no one likes him because he is black and no one wants anything to do with him, that’s why he lives in the barn by himself with just magazines to read.
