Is it normal to think that someone is not your friend ?

Stupid bitch.

It sounds like your taking too much of her shit, and she's getting real comfortable dishing it. So I suggest next time she says something along the lines of the dirty-shit-rag comment, you look at her in the eye and say something equally offensive. Hurt her feelings. Make people laugh at her. Also, she IS implying your a fucking idiot by asking you those same questions.

Be mean. She's doing it. You do it, too.
