In chapter 4, the majority of the workers head into town, and Lennie stays behind to play with his dog. Lennie then notices a light coming from Crooks's room and enters without being invited. Crooks immediately chastises Lennie for intruding and says, "You go on get outa my room. I ain't wanted in the bunkhouse, and you ain't wanted in my room" (Steinbeck, 33). When Lennie asks why Crooks isn't allowed in the bunkhouse, Crooks responds by saying that he is forbidden because he is black and the white workers on the ranch claim that he stinks. Essentially, Crooks resents the fact that he is marginalized and discriminated against because of his race. He has become a lonely, upset individual who is sick of being treated unfairly. Crooks feels that if he is not entitled to enter the bunkhouse, then other men should not be allowed in his room. In an attempt to get even with the prejudiced workers and express his displeasure, Crooks refuses to allow them into his room. However, Crooks makes an exception for Lennie and Candy when the men head into town.
