George, unlike other men, has a companion and friend in Lennie. Because of this, Lennie makes George feel special. They are different from all the other guys, and George realizes only too well that they have a special bond. At the ranch, George often plays solitaire, a game for one. Without Lennie, George would be a loner. Even though George gets frustrated by Lennie's mental weakness, he also feels compassion for his friend. Lennie offers George the opportunity to lay plans, give advice, and, in general, be in charge. Without Lennie, George would be just like the other hands, but with Lennie, George has a strong sense of responsibility. In the end, he even takes responsibility for Lennie's death. George also understands that Lennie does not have an adult's sense of guilt and does not understand death or murder beyond it being a "bad thing." George makes it possible for Lennie — sometimes — to understand at least partial consequences of his actions. Unfortunately, George does not realize how dangerous Lennie can be, and this lack of foresight adds to the downfall of their dream.
Their dream also sets George apart from the others because it means he and Lennie have a future and something to anticipate. Unlike Lennie, George does not see their dream in terms of rabbits; instead, he sees it in a practical way. Their farm will be one where they can be independent and safe and where he will not have to worry about keeping track of Lennie's mistakes. They can be secure and in charge of their own lives. However, Lennie is the one who adds the enthusiasm because George never really believed they could swing this farm of their own. He mostly uses the story to give Lennie something to believe in for their future. Only when Candy offers the stake does George actually begin to see that this dream could come true. But, realist that he is, George tells Candy over the lifeless body of Curley's wife, "I think I knowed from the very first. I think I know'd we'd never do her. He usta like to hear about it so much I got to thinking maybe we would [be able to have the farm.]" In the end, George Milton is man alone once again.
