Ask her out. If she refuses, she might actually be a lesbian. Alternatively, get to know her or her friends better. Then you might learn whether or not she is a lesbian.
I think I will. Funny you should suggest getting to know her friends, because the only friend I ever see her with is a gay guy. Could be a GBF or a brother in gay arms. I will see. Don't think I'll be getting to know him though as I have no classes in which socialising with him would make sense.
It's really hard to tell whether she's just a normal "outsider" girl or a college lesbian. Everything about her could be used as an argument in both directions. No college for another week + 1/2 but I'll let you know how it goes when I'm back... Need this post to keep me honest
