How does Whit refer to Curley's wife? What does this do for our (the audience's) perception of Curley's wife?

Whit says to George that it "seems like [Curley's wife] can't keep away from guys." Curley's wife is regarded as trouble by all of the men, not just Whit. She is referred to as a "tramp", a "bitch" and a "tart" - her physical description, described as "heavily made up" and lips painted red, certainly supports this belief. In particular, her actions likewise get the men into trouble by her attempts to find friendship with the men. She, like many other characters in this novel, craves company and friendship, but this is misinterpreted. Especially with her conversations with Lennie, she shows herself to be incredibly vulnerable, and to have a dream just like other characters in the story. Her treatment at the hands of the men and her husband help the audience to feel pity at her situation, whilst at the same time she does not help herself by her actions.
