He thinks that they won't get the land because they don't have the money
Crook's opinion of George and Lennie's desire to get land is that they are crazy. Crook believes they will never achieve that dream because no one ever achieves that dream.
Crooks is initially incredulous about George and Lennie's dream of owning land, as he has seen many others fail to achieve their dreams. However, he eventually becomes interested in the idea and expresses his own desire to be a part of their plan.
He states this when George goes away for a while with the men and Lennie appears in Crooks room. They then have a conversation, in which Crook says he needs just like Lennie and George.
Crooks wants to join George and Lennie in their dream and embraces the fact that they might fulfill this dream due to them having money and having the land picked out (everything is figured out thanks to Candy). Crooks then offers to help at this new location by hoeing the land.
Crooks initially doubts George and Lennie's dream of owning land as he has never seen it come true for anyone like them. However, after hearing them speak passionately about their vision, he starts to believe in it as well.
George gets frustrated because he does not want others to find out about moving to the ranch. If Curley or the Boss finds out that they want to move away, they may cut George and Lennie as workers and therefore they will not be able to move to the ranch.
Crooks is initialyy wary and skeptical of George, Lennie, and Candy's dream of having their own place because he has seen many similar dreams fall through in the past. However, he becomes more intrigued and hopeful as he sees the genuine desire and determination in their hearts to make it a reality.
In John Steinbeck's novel "Of Mice and Men," Lennie and George share a dream of owning a piece of land where they can live self-sufficiently and free from the difficulties of working for others. They envision themselves living off the land, with Lennie tending the rabbits and George overseeing their home. This dream represents their desire for independence, stability, and a sense of belonging.
Crooks initially doubts George and Lennie's chances of getting land and owning a farm, unable to believe their dream will come true. However, he becomes captivated by their vision and wishes he had someone to share a dream with. Ultimately, he becomes hopeful that the dream could be a reality, offering to work on the farm with them.
George manipulates Lennie by taking advantage of Lennie's simple-mindedness and dependence on him. He often convinces Lennie to do things or not do things by appealing to Lennie's trust in him and his desire to please George. George can be both loving and controlling towards Lennie, using their close bond to control their situation.
Curley's wife tells Crooks, Candy, and Lennie about her loneliness and desire to connect with someone. She confides in them, sharing her frustrations and dreams, hoping to bridge the gap between herself and the other ranch workers.
At first, he finds it ridiculous; however, he is charmed by its simplicity and wishes to make it a part of his future too, but when he Lennie leaves Crooks' room, he is resentful and condemns the dream as an impossibility.
