What is Crooks's initial response to Candy's account of the dream farm and what evidence is there that his attitude changes?

At first, Candy says that he is nuts.  He does not believe a word of it.  He says that he has seen hundreds of men who have the same dream and say the same thing.  To be fair to Crooks, he has been on the ranch for a long time; and he has probably seen his fair share of people who had the same dream. Here are the words of Crooks.

At first, Candy says that he is nuts.  He does not believe a word of it.  He says that he has seen hundreds of men who have the same dream and say the same thing.  To be fair to Crooks, he has been on the ranch for a long time; and he has probably seen his fair share of people who had the same dream. Here are the words of Crooks.

Hunderds of them. They come, an’ they quit an’ go on; an’ every damn one of ‘em’s got a little piece of land in his head. An’ never a God damn one of ‘em ever gets it. Just like heaven. Ever’body wants a little piece of lan’.

When Lennie and Candy begin to speak of the land more, Crooks begins to change. What changes him is the mention of money.  Lennie and Candy say that they have the money ready.  Moreover, they also have a piece of land picked out.  But perhaps more importantly, Crooks begins to believe, because Lennie and Candy really believe.  Here is the quote:

Crooks asked, “You say you got the money?"

“Damn right. We got most of it. Just a little bit more to get. Have it all in one month. George got the land all picked out, too."

Crooks reached around and explored his spine with his hand. “I never seen a guy really do it,” he said.
