I think because she moved to a new area and you’re the one she’s living with she’s probably going to assume that she could kind of tagalong with you and your friends will be her friends so I think it’s important that you just don’t invite her out whenever you’re doing individual stuff but I think to put the wall up and say I’m not going to be her friend is pretty nasty of you honestly especially because you know that she doesn’t have anybody I can’t see why it would be such a big issue to offer to go out to lunch with her and study together or some thing. There are extremes to everything but telling your roommate you don’t want to be friends is not cool. I almost feel like you shouldn’t be asking for a roommate if you’re going to cop an attitude like that because WTF girl. It would be different if you found out she was wiping her ass with your toothbrush but she’s done nothing to you and you just don’t like her because.. she’s eager to have friends? Yikes. It doesn’t make you sound like a very nice person.
