It might actually be easier. She might talk to you every now and then (but if you show her you don't really like small talk she probably won't be talking to you much) but you will get more privacy - I mean, you are both girls so it's no big deal if she sees your naked or realizes you are on your period. With a guy it might be awkward.
And who knows, maybe you will actually become friends and she will help you out socially?
