This character represents black men who are forced to live in isolation because of racism. Crooks has received his name due to his crooked past. He lives alone, but when Lennie starts talking with him, Crooks tries to befriend him. It means that this character is fed up with loneliness, and he needs communication. He even asks Lennie if there is a place for him in the future farm because he will be eager to hoe in the garden. Although he sometimes behaves weirdly (when he tries to fool Lennie telling him that George has left forever), Crooks dreams about free simple life where he can have friends just as everyone else.
