why is curley's wife lonely

Whenever Curley's wife shows up we see her loneliness. It pours out of her in resentment and disillusion.

"I never get to talk to nobody. I get awful lonely."

"What's the matter with me? Ain't I got a right to talk to nobody?"

"Seems like they ain't none of them cares how I gotta live".

Curley's wife is a possession. She represents such loneliness that she doesn't even get a name. Curley is abusive although we never see them together. She spends much of the time "looking" for Curley although she is really looking for other companionship.
