George and Lennie seem to be two lonely men. George has to always keep an eye on Lennie and therefore Lennie is a burden to him. Lennie on the other hand is lonely, but he is too dim to understand. He seems to live in his own world, and evolves everything around whether it pleases George or not. But they have something that all the other men have not got, and that is a true friendship. Lennie is there for George to keep sane, while George is there to help Lennie. George likes to talk to Lennie most of the time about their dream ranch. He says to Lennie that guys like us are the loneliest people in the world but he comments on themselves "With us it aint like that. We got a future. We got somebody to talk to that gives a damn about us.." (p.32) This just shows that they both enjoy talking to each other, making each other happy. But later on in the book, George loses Lennie, as he kills him himself. When one of the members of a friendship is removed, there is much misery. When Candy lost his dog, he kept thinking about him. He felt he should have shot his dog himself, not a stranger. When George had to shoot Lennie, he felt terrible. He had just shot his best friend, his only friend in the world. Because of this, he has to live the rest of his life alone and knowing that he killed his only friend. But I think he did the right thing. I think it shows their strong friendship. George did what was best for himself and for Lennie, a she could not watch Lennie die miserably in pain, getting brutally killed by George. He wanted George to die peacefully, thinking about the thing he loves about the most-rabbits. He knew Lennie would have died in slow and cruel way if he left it for Curley.
After George killed Lennie, it seems that he would have a better life without him, but really he would have a worse life and would turn out like the other ranch workers. He will suffer from loneliness and will have no true friends. Of course, his dream will never come true as he could...
