Curley's wife feels like she can take advantage of the guys that are left. Unfortunately, she thinks she needs to use her womanhood to do it. She's heavily made up and breathing hard. She studied her nails and let her eyes slyly move from man to man. She regards the men with amusement.
Her complaint is that she has no one to be in any real relationship with. Although she is married to Curley, they really aren't even friends. She tries to befriend the men, but they don't want to get in trouble with Curley. She has real problems with not being around any women.
I don't really feel sorry for her, that's what marriage is. Sometimes it's tough, but she made a decision and now she has to live with it.
