Join Lennie and George's dream
George didn't want Lennie to have a mouse because he was concerned that Lennie would accidentally kill it with his strength, and he also didn't want Lennie to get sick from handling the mouse and die.
Curly does not want to bring Lennie unharmed because he is angry and seeking revenge for Lennie's actions, which resulted in Curly's wife's death. He sees Lennie as a threat and wants to make him pay for what he did.
Ketchup!
George knows that Lennie will want to sleep in the barn on Friday night because Lennie always wants to tend the rabbits there, and it brings him comfort and joy. Additionally, George wants to keep Lennie away from the other ranch workers because he knows they can be mean and may potentially harm Lennie due to his disabilities.
George doesn't want Lennie to drink the water because it might not be safe, especially if it's contaminated. Lennie has a habit of impulsively drinking from unknown sources, which could be harmful for his health. George is trying to protect Lennie from potential harm.
Slim has the Puppy that Lennie Wants, that George Promised him to replace the dead mouse.
The main two main reasons why George didn't want Lennie to have a mouse are that he kills the mouse without knowing/realizing his own strength when the mice bite him, and Lennie bothers George by bringing that same mouse but Lennie doesn't know that bothers him. Lennie acts like a child mental.
Lennie says he will go live in a cave if George gets fed up with him and does not want him around anymore.
