what Steinbeck is saying is saying about candy's loneliess

Candy is isolated in that after the loss of his hand he is unable to work alongside the other men and is reduced to the role of swamper. Once his dog has been shot Candy has little else to live for and is desperately lonely. He is powerless and afraid of the future. He does not go into town with the other men, and sees the inclusion in George and Lennie’s dream as the only way out.
