What does curley's wife do to finally gey crooks mad at her?

Answer 1

Crooks finnaly gets mad at Curley's wife when she starts flirting with Lennie.

Lennie smiled happily.' That's him,' he said. 'That's the guy, an' he's gonna let me tend the rabbits myself' 'Well, if that's all you want, I might get a couple rabbits myself' (Curley's Wife- pg.79)

That's when Crooks finally reaches breaking point.

Crooks stood up from his bunk and faced her. "I had enough," he said coldly. " You got no rights comin' in a coloured man's room. You got no rights messing around in here at all. Now you jus' get out, an' get out quick..." (pg. 79)

Answer 2

Curley's wife belittles Crooks by threatening to have him lynched. She diminishes his self-worth and asserts her power over him due to her privilege as a white woman, ultimately provoking Crooks' anger and frustration.
