That being said, you can't know for sure, so I would just give her a call. Don't make to much fuss about it, be authentic and yourself (I know, easier said than done), say something to the effect you enjoyed talking to her and ask her if she's interested to have a drink with you. The worst thing that can happen, is that she says "no". It is not likely that she will do that in a harsh way. And if she does, just accept that and look at it as a new experience.

Well, thank you. I think I should try something along those lines.

P.S. I WOULDN'T ask her if she has a boyfriend: it's too obvious and the answer could be embarrassing to both of you.

Yeah, I wouldn't do that. I couldn't, even if I wanted to anyway.
