Lennie Small is huge and lumbering and, in many ways, the opposite of George Milton. Where George has sharp features and definite lines, Lennie is "shapeless." Often he is described in terms of animals. He lumbers like a bear and has the strength of a bear, but his actions are often described like those of a dog.
Lennie's personality is like that of a child. He is innocent and mentally handicapped with no ability to understand abstract concepts like death. While he acts with great loyalty to George, he has no comprehension of the idea of "loyalty." For that reason, he often does not mean to do the things that get him into trouble, and once he does get into trouble, he has no conscience to define his actions in terms of guilt. Lennie only defines them in terms of consequences: "George is going to give me hell" or "George won't let me tend the rabbits." He is devoted to George like a dog is devoted to its master, and he tries to follow George's commands. There is a childlike wonder in Lennie that can be seen when he first sees the pool of water and slurps down huge gulps of water like a horse.
