The first chapter offers a small description of George that will take on life as the book progresses. Steinbeck writes:
The first man was small and quick, dark of face, with restless eyes and sharp, strong features. Every part of him was defined: small, strong hands, slender arms, a thin and bony nose. Behind him walked his opposite, a huge man, shapeless of face, with large, pale eyes, and wide, sloping shoulders; and he walked heavily, dragging his feet a little, the way a bear drags his paws.
Even though this description is short, it shows that George is quick (sometimes short-tempered), smart, and aware. He is all of these things. He takes care of Lennie and knows what to do to survive.
As we read the story, we also discover that George is caring. Here is a genuine bond of friendship between George and Lennie. Moreover, George will put himself out there for Lennie. I should also add that George is also a dreamer at times. He really thinks that he can get a place of his own with Lennie.
Finally, in the end George sees that he must kill Lennie for his own sake. It is hard decision, but he makes it.
Slim said, “You hadda, George. I swear you hadda. Come on with me.” He
led George into the entrance of the trail and up toward the highway.
