He tried to buy himself into a friendship with George and Lennie by offering them money to go towards the ranch they plan to buy. This shows how he is lonely because he if he buys himself into this then there is a chance he will not die alone. Early in the book we read that his dog is shot because it was too old and was just a general nuisance to the other workers, so the other workers persuade Candy to let them shoot it. Candy does not let his dog go without a fight because his dog is his only true friend, but in the end he just gives in.
The next character I am going to talk about is Crooks. Crooks is a black stable buck, who lives and works in the stables. He is a crippled Negro who has no real friends and only has books to keep him amused. He lives away from the other labourers because of his colour. Also he is treated unfairly due to his race, for example the only time Crooks ever gets to socialise with the other workers is when they play horse shoe, a game commonly played on the ranch, but even at this they don't talk to him much. However I feel crooks looks onto this positively because living in his own space means that he has more space to keep personal possessions, which the others don't have. .
As he lives on his own he has become very secluded and insecure. We can see this when Lennie goes into the room Crooks lives in, Crooks immediately starts to defend his space and try to get rid of Lennie. He even said " You got no right to come in my room". Even though Lennie puts on his pathetic smile, he still rejects him. After a little while Crooks becomes more comfortable in Lennie's company and starts to open up to him. This shows us how secluded Crooks has become because when Lennie enters he just completely shuts him out, he has been on his own for so long he just doesn't want to know. He starts to talk to him about how lonely a man can get if he hasn't got any friends. This shows us that he is so desperate just to talk to someone that as soon as Lennie comes in he jumps to talk to him.
