What kind of person does Curly seem to be?

Curley is a mean little man with a little man's complex. He consistently tries to prove he's tough, picking fights, acting in a condescending manner, and threatening others whenever the opportunity presents itself. He's jealous, possessive, and spoiled.

“He can talk if he wants to tell you anything.” He nodded slightly to Lennie. “We jus’ come in,” said Lennie softly. Curley stared levelly at him. “Well, nex’ time you answer when you’re spoke to.” He turned toward the door and walked out, and his elbows were still bent out a little.

He said, “This guy Curley sounds like a son-of-abitch to me. I don’t like mean little guys.” “Seems to me like he’s worse lately,” said the swamper. “He got married a couple of weeks ago. Wife lives over in the boss’s house. Seems like Curley is cockier’n ever since he got married.”

Whit said, “I see what you mean. No, they ain’t been nothing yet. Curley’s got yella-jackets in his drawers, but that’s all so far. Ever’ time the guys is around she shows up. She’s lookin’ for Curley, or she thought she lef’ somethin’ layin’ around and she’s lookin’ for it. Seems like she can’t keep away from guys. An’ Curley’s pants is just crawlin’ with ants, but they ain’t nothing come of it yet.”
