Curley’s wife is a tease, and she is constantly flirting with the men on the ranch.
When George and Lennie arrive at the ranch, Curley is newly married. It is obvious from the beginning that his wife is dangerous, because she is always looking for him and he is always looking for her.
Candy comments that she seems to be looking at other men.
“Yeah? Married two weeks and got the eye? Maybe that’s why Curley’s pants is full of ants.” (ch 2)
She uses the excuse of looking for Curley to travel around the ranch amongst the men. These flirtatious bouts do not go unnoticed, and it is soon rumored that she is having an affair with Slim, or several other men on the ranch.
“I seen her give Slim the eye. Slim’s a jerkline skinner. Hell of a nice fella. Slim don’t need to wear no high-heeled boots on a grain team. I seen her give Slim the eye. Curley never seen it. An’ I seen her give Carlson the eye.” (ch 2)
Candy concludes that Curley married a tart. There are certainly some men who feel like George that Curley’s wife is trouble, but others will probably take her up on her
