Things will never get anywhere at school. It's a good place to get to know her better, but there are too many watching eyes for any kind of real flirting.
I'm thinking I'll just ask her to come along with me to some kind of social event that involves drinking, but it would have to be one that I think would appeal to her. I don't think she'd be a fan of my usual Friday night dive bars at this point.
Btw, I was walking up my stairs just now, and a pretty cool guitar riff came to me, and I actually managed to figure it out once I sat down with a guitar (I've lost some great riffs while in the process of trying to figure them out on guitar; I wish I had a better ear), but I'm not sure if it's been done before. It probably has.
