In the book Of Mice and Men, describe Curley's wife. What's the problem about her?

Curley’s wife is very young. One of the men refers to her
as “the kid.” She is called “jailbait” several times. “Jailbait” can only mean a
promiscuous underage girl who can get men sentenced to prison on a felony count of
statutory rape. She is overly made up and overly dressed for the ranch setting,
suggesting that she looks like a young girl who is trying to look older and sexier. When
she is telling Lennie about herself in the barn, she reveals that she almost ran away
from home with a man when she was only fifteen and then married Curley to get away from
her mother. She is probably only sixteen. Why would Curley marry such a young girl?
Well, he obviously has an inferiority complex because of his small size, and he could
conceivably feel inadequate with a mature woman. (He may even be inadequate with his
adolescent bride!)

Steinbeck created Curley’s wife. He must
have made her extremely young for a purpose. Her immaturity would explain why she is so
flirtatious and so restless. Her mother couldn’t control her, and now Curley can’t
control her either. All the men regard her as potential trouble. Specifically, they
think one of the farmhands will get sexually involved with her and then either Curley
will kill him or he will get sent to prison for statutory rape—or even rape, if she
should decide to tell the story that way.

Lennie is
characterized as being obsessed with petting small, soft animals and always killing them
by petting them too hard. He is more likely to be attracted to a young girl than an
older woman, and Curley’s wife is sufficiently naïve and indiscreet to flirt with a
retarded giant in an isolated setting, although she knows he kills little animals and
has maimed her husband. The fact that she is still quite young and undoubtedly has the
build of a frail adolescent girl explains why Lennie could break her neck so easily. An
older woman would not get so close, would put up more of a fight, and would not be so
fragile.

There are many references to an incident in Weed
in which Lennie was accused of attempted rape. The female involved is always referred to
as a “girl,” never as a young woman. She could have been even young than Curley’s wife.
When George sees Curley’s wife’s dead body, he suddenly understands that Lennie is
developing a sensual interest in young girls, and that he is just as capable of killing
them as he is of killing the little animals he
handles.

“I
should of knew,” George said hopelessly. “I guess maybe way back in my head I
did.”

George realizes that
Lennie is a menace to society and that he himself is guilty of the death of Curley’s
wife because he is responsible for Lennie. He helped Lennie escape from the lynch mob in
Weed, but he is not going to help him escape again. That is why he steals Carlson’s
pistol. He intends to kill his friend from the time he leaves the ranch to meet him at
their prearranged rendezvous by the river.
