A strange chemistry...

So I went to the bar one night to give some friends a ride home. I was sober they were not. One of their friends was there and she was really drunk that night. She was taking a cab home and was chewing me out for giving my friend a ride. Obviously a silly drunken thing that she regretted the next day and hardly remembered.

Anyway, I'm in a bowling league and she works up there and is our waitress. We always chat there and she's really flirty with me...but is sometimes kind of weird in a mean way. Like she makes comments and I don't know if that's her way of flirting or if she's just kind of got a mean streak.

It's strange and I think she's really cute...and I'm attracted to her but I'm not sure if I'm really attracted to her personality. And one of my friends actually slept with her too, which isn't a big deal I guess...but just a little weird for me too.

So I'm not really sure what to do, if I should see if she wants to go out sometime or just leave that alone.
