Curley beat up Lennie in "Of Mice and Men" out of anger and jealousy. Curley was upset over his wife's flirtatious behavior towards the ranch workers, including Lennie. Being a small man, Curley also took out his frustrations on Lennie to assert his dominance and power over him.
Curley was in the bunk room beating up Lennie. Curley was looking for his wife and saw Lennie laughing. Curley thought Lennie was laughing at him when he really wasn't. Curley then started to beat up Lennie while George is screaming to Lennie to fight back. Lennie then grabs Curley's fist as he is about to punch him again, and Lennie crushes Curley's fist. The damage to Curley's fist was so bad he was taken to the hospital. Slim forces Curley to say his hand was crushed by a machine. There were hardly any bones left in Curley's hand, and Curley was crying.
The book didn't necessarily state that Curley hated Lennie; however, as slim said in the beginning, Curley is like a "bunch of small people piled up". Since Lennie is known as the "big" (size) character in the story, Curley obviously wanted to beat him up. One of the other reasons could also be his mental disorder (Lennie).
George wants Lennie to stay away from Curley and his wife because he knows that Lennie is not able to understand social cues and may inadvertently get into trouble, especially with someone as volatile as Curley. He wants to protect Lennie from dangerous situations and avoid any conflict that could jeopardize their dream of owning a farm.
Curley attacks Lennie out of rage and insecurity. He is a small man who feels threatened by Lennie's size and strength, and he targets Lennie in order to assert his dominance over him and prove his own toughness to the other ranch workers. Curley's aggressive behavior reflects his own feelings of inadequacy and a desire to prove himself.
George tells Lennie to fight back and defend himself if Curley hits him. George wants Lennie to stand up for himself and not allow others to take advantage of him.
Curley thinks that Lennie was laughing at him (when he wasn't) and he has been wanting to pick a fight with Lennie because he dislikes people taller than him because he isn't very tall himself.
He took an arrow to the hand.
Well at first he tells him to stay away from him, but when he starts to get punched by him he says to fight him.Two things that George tells Lennie to do with regards to Curley are to "keep his distance" and "stick up for himself".
Curley's wife visited Crooks, Candy, and Lennie in the book "Of Mice and Men" by John Steinbeck. She went into Crooks' room looking for Curley and ended up talking to the men there, revealing her loneliness and desires.
If you're talking about the book 'of mice and men', they pretty much hate each other;In one scene, Curley beats up Lennie for no real reason, George tells Lennie to fight back, so Lennie does, not meaning to break/seriously injure Curley's hand. After this incident, Curley hates Lennie, (obvious) and hates George for being Lennie's friend, and not being on Lennie's side.Something that doesn't help their relationship, is how protective Curley is over Curley's wife. Curley's wife is very flirtatious, and tries to have conversations with both George and Lennie. Curley hates George for flirting with his wife, even though it wasnt his fault. He is also too strict with his wife, which makes her go looking for even more trouble.Near the end of the novella, Curley's wife tries to talk to Lennie in the barn, but they get into a bit of trouble, by Lennie accidentally killing her. he then runs away, knowing how much trouble he will be in with everybody. When Curley finds out what happened, he automatically blames Lennie without proof, so therefore hates George even more.Hope this helps, and if you watch the film, it should be a bit clearer.
Because he think curly will see him with his wife and will beat up lennie, and they will lose their jobs, and because he doesn't want to repeat the accident that happened in weed with the girls dress...:)
When Lennie does not want to talk to Curley's wife she begins to feel like everyone around her wants nothing to do with her including Curley himself. She also does not understand why nobody wants to talk to her so she asks what the problem is with someone trying to get a little attention, as well what the problem is with her trying to make conversation.
