How do George and Lennie react to Curley's wife? What does "she's got the eye" mean? And what is the intended effect on the reader?

George is weary of Curley's wife; in fact all the men, except Lennie are scared of Curley's wife. She is a temptress of sorts. She moves from cabin to cabin flirting with the men. The reality is that she is desperately lonely. The men don't want to talk to her because Curley, the bosses son, is hot tempered and can get them fired from a job they desperately need. Lennie thinks like a seven year old. He finds Curley's wife soft and misunderstands her advances. Lennie does not understand the repercussions from Curley. George knows Curley's wife "has got the eye" meaning that she uses men and gets them in trouble.
