What is Candy's attitude towards other characters in the book Of Mice and Men?
More than anything else, Candy just wants to be useful to other people. His age and disability act as a constant reminder of how he's been discarded by society. He needs a place in life where he can make some mark upon the world. It's not surprising, then, that Candy jumps at the chance to buy into George and Lennie's dream of owning their own farm. So his attitude towards George and Lennie is generally positive.
The same can't be said in relation to Carlson. When Carlson proposes that Candy shoot his dog, it brings home to him how increasingly useless he's becoming on the ranch. In the pathetic figure of his decrepit old dog, Candy gets a chilling foretaste of his own fate.
Candy also doesn't have much time for Curley's wife, but then no one does, really. But in his case he has a particular reason for not liking her. Her overpowering sexuality constantly reminds Candy that, as he's severely disabled, he's considered something less than a man. Curley's wife also cruelly taunts him, mocking Candy as one of the "weak ones" no longer permitted to visit the brothel.
Candy is generally welcoming to all characters. As the man who greets George and Lennie, he is especially kind and informative. His congenial behavior suggests he longs for friends and is therefore approving of George and Lennie from the beginning. As the story continues and he learns of their dream, he is anxious to join and willing to offer a great sum of money to join their idea.
Candy classifies Curley's wife as a tart. He does not trust her and warns other men of her flirtatious behavior.
When Candy's dog smells up the bunkhouse because he is old, Carlson encourages that it is time for the dog to be put to sleep. Candy disagrees, but reluctantly allows Carlson to take care of this situation to maintain his relationships with the entire group. Although it hurts him greatly, he makes this sacrifice to maintain the guys' respect.
Candy does not like Curley, the boss' son. He thinks Curley is mean and that he's pretty "handy". What he means is that Curley is pretty good in a fight.
