George is not comfortable with the idea of Candy and Lennie visiting with Crooks. Certainly, part of this is the residual attitude that White society held towards people of color, specifically African- Americans. This is not something that is revealed in anything that George says, but rather it is something that is intimated and something that is evident in the manner in which George looks at the setting. The only thing that George openly conveys is his discomfort with the idea that George and Candy are sharing the dream of the farm with someone else. George is seeking to keep things as quiet as possible regarding their dream. The only reason that Candy knows is because of his money contributed. For George, the idea that Lennie and Candy would be discussing this dream in front of another person is uncomfortable for George. It can be inferred that Crooks, being African- American, represents a level of difference that someone as defensive as George would not be able to fully appropriate. After being humiliated by Curley's wife and seeing George's reaction, Crooks himself withdraws from his participation in the dream, conveying the level of disapproval and resistance that George displays towards Candy and Lennie visiting with the stablehand.
