key quotes that are said about carlson that link to loneliness.

carson represents the men George describes as “the loneliest guys in the world”. He is outwardly friendly, but really selfish. He finds the smell of an old dog offensive so the dog must be shot. He has little regard for the feelings of the dog's owner. At the end of the novel, as Slim goes to buy George a drink, and comfort him, it is Carlson who says to Curley, “What the hell...is eatin' them two guys?”
