To clarify: Only one of them is a bitch. Just saying I said something you were going to say doesn't mean anything against me. I think she was just worried about her grade in the seminar, because I remember before she asked me how she did. She just seemed to be saying "shit I didn't get to say something". I mean, during the seminar, this other guy (who I'm sort of friends with but he can be an asshole, it's complicated) and I started talking at the same time and I was like "go ahead I'll go after", and he said what I was going to say about the society in the book actually being good. And then when I started I said that he said exactly what he was going to say, but it wasn't in a bad way. It was just like "damnit"; obviously I didn't have anything against him and I think she was saying the same type of thing. She's also generally a nice and smart person, so I really don't think she was being a bitch.
The OTHER girl... She's just a snobby bitch.
We worked in assigned group projects creating a PowerPoint of our own Utopias, and she was in my group. First of all, she doesn't understand the concept of a fricking interactive PowerPoint, and doesn't understand that you can't put photos over text, but that's not relevant here...
I tried to be nice to her in our group project but she's unbearable. I remember before I thought she was a bitch, I ran into another person in my group in the bathroom and she was like "I'm so sick of _____, she doesn't understand that it's not just her project."
And at lunch today, my friend told me that awhile ago she was sitting near her because her table was moved or something and she said something like "I don't like them but I'll pretend to."
Then GTFO! What the hell.
So she's just not a nice person in general.
I remember, before I knew her, I thought she was a nice person (ok, I gave her the benefit of the doubt), and her sister was complaining about her (she was giving me and some other people a ride and she started complaining about her sister). It kind of sucks for her sister who has to give her rides every morning, because this girl fills up a coffee cup in the morning without a rim and takes it into the car and it spills everywhere. She's actually like the polar opposite of her sister; her sister is really smart and nice. It's kind of amazing that they're related.
Ok, I think I just went off on a bit of a tangent there.

Anyway, I'm not going to start a rumor about her, that just seems mean unnecessarily. I mean if she starts talking to me ever then I'll bring it up, but I'm not going to go out of my way too. It's not like it'd be productive, so there's no point in that, since she's just a bitch. But at the same time if she starts talking to me normally I'm not going to act like it didn't happen.
