According to Candy, what is Curley good at in "Of Mice and Men"?
In Chapter 2, Candy, the old swamper, tells George and Lennie that Curley is good at boxing. This foreshadows the conflict to follow between Curley and the other men, especially Lennie. It also gives proof to Curley's personality trait of being scrappy.
In addition, Candy saying that Curley is good at boxing gives support to the fact that Curley suffers from "Napoleon Complex" a.k.a "short man's syndrome."
