Lennie's Un-Acceptance

With Lennie's mental disability, fitting in with others is quite difficult. What makes fitting in for Lennie even more difficult is the fact that the characters in the novel are not very intelligent, seeing as though they work on a ranch and the way they choose to speak.  With very low intelligence, the workers on the ranch don't understand why Lennie behaves the way he does, so they choose not to become close to him.  After Lennie killed Curley's wife, the workers instructed George to kill Lennie so he couldn't cause any more harm to people.  The decision to kill Lennie was easy for the workers to decide because Lennie was never close to them.
