How did you see loneliness affect a character's actions towards others

When I saw this it was when Lennie went to see Crooks. When Lennie entered Crooks room Crooks clearly did not like him in his room. I saw this when Crooks said "you got no right to come in my room. This here's my room. Nobody got any right in here but me." I think loneliness affects Crooks because he has no friends. Another reason is "Cause I'm black." Since Crooks is black he is treated differently which is why he has no friends. I believe these are the two reasons Crooks gets affected by not having relationships with people and how that affects his actions.


Do you believe this to?
