I found out that one of my other friends is looking for a roommate, so we're going to see if we can work it out. I haven't told the two girls yet just in case something falls through and I have to room with them anyway, but I'm trying to find out within the next couple of days so that they can have notice pretty far in advance. There are a few things I'd like to clarify, though.
First of all, I was going to room with these two people--one, who I'll call K, has been one of my best friends for years. We talk about problems and whatnot and hang out a lot. I don't want to stop being friends with her, but I understand that once we get to college, our friendship dynamic will be much different because we'll probably be part of two different "circles" of people. I understand not talking about stuff around people who aren't interested in the same thing, so it's not an issue when we're at home, I guess. It's not necessarily that she has a problem with it, it's that she's disinterested in it, and I think she unintentionally comes off as condescending about it. She has no problem being friends with me, but if I start talking about something "nerdy" it's...embarrassing for her or something? I don't really know how to describe it. I guess a similar example would be if you liked _____ band and your friends weren't really into music, you probably wouldn't constantly bring up the band around them because of the way they would react or behave.
The other girl, S, I literally met the week before we went down to go apartment hunting. She was nice for the most part though, until something like that came up. Something I don't entirely understand, though, is why this is happening. S is really into anime (deep cuts, too, not just the stuff everyone knows and not just "omg i ship it<3" like on Tumblr) and even went to Otakon and spent $200 on anime merch and whatnot. From what I understand, most of her friends are more "normal" (the word she used, not me), but still. K is really into Doctor Who, but from what I can gather on Tumblr and real-life interactoins, Doctor Who fans just don't consider themselves that "type" of person either. While part of my concern is that they'd make comments to my friends and to me, another concern in this regard is that they'll have friends over too and that those friends will be even ruder about it.
Another thing is that it's not like full-on bashing. They're not angry that I'm into any of this stuff or that my friends are. It's just like when friends mess with each other, but how after a while, it becomes much more grating than you initially let on. I know they don't mean for it to be so disrespectful or aggravating, but it just is.
Before I left to stay at home for a few semesters, I roomed with a friend who was really into all the same stuff that I am, and it was extremely liberating and great. I guess I got a little spoiled by that to the point where anything else seems unsatisfactory, haha. That's why I'm worried that I'm being petty even though I do have some other, more "legitimate" concerns (such as our vastly different sleep schedules). However, if it doesn't work out with my other friend, it won't be the end of the world. I mean, they're clean people and all that.
I didn't want to quote everyone, but since there were a bunch of responses, I just have this large block of text.
tl;dr - I think rooming together would not only drive me crazy, but destroy the friendship that we do have. They're not bad people, it's just an incompatibility issue. I'm trying to work something else out within the next few days, and if it doesn't work out, I'll fall back on rooming with these two. Thanks for all the advice!
