Who is Curley?

Curley is the son of the ranch owner, Curley is a man of short stature who is nevertheless a formidable boxer. Curley is aggressive, boastful and cocky, with a volatile temper and a tendency to provoke conflict with the weak (he has "small guy complex") , as he does with Lennie. Part of Curley's bravado stems from anxiety over his new wife, who everyone widely suspects of being "a tramp." He spends a great deal of time monitoring her, believing her to be off with other men when she is not under his supervision.
