why does crooks conceal his pleasure with anger when candy comes in? what ironic thing does candy say to crooks, cosidering crooks complaints and loneliness

Crooks is conflicted inside. He is desperately lonely and welcomes Candy's visit. At the same time he protects the little hovel he is in as his space. Crooks is segregated from other parts of the ranch. His little space represents a shred of dignity. Candy says, “You got a nice cozy little place in here.” This is ironic since it is basically in the horse stable with the smell of manure.
