George longs for his own land just as much as Lennie does, but he mostly uses the dream to give Lennie and himself something to look forward to.
George travels around from ranch to ranch with his friend Lennie as a migrant worker. The migrant life is difficult and lonely, and most men travel alone. George looks out for Lennie because Lennie has a mental disability.
George tells Lennie that they have a future, unlike most migrants, because they have each other and they have a dream.
"O.K. Someday- we're gonna get the jack together and we're gonna have a little house and a couple of acres an' a cow and some pigs and-"
"An' live off the fatta the lan'," Lennie shouted. "An' have rabbits….” (ch 1)
George uses the dream to calm Lennie down, but he cares about it too. When Crooks gets involved, it seems more and more possible. However, Lennie accidentally kills Curley’s wife, and George realizes that the dream is not possible.
George said softly, "-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." (ch 5)
When Lennie kills the girl, he kills their dream. George has to come back to reality and admit to himself that there is no way they can get their ranch. It was nothing more than a fantasy. George not only realizes that, he also realizes that he has to kill Lennie himself to put him out of his misery.
The dream kept George and Lennie going, and George came to want it as much as Lennie. Sadly, the dream died with Lennie and George was left even more alone.
