Backstory: Last year I saw a beautiful girl sitting, eating alone at a dining hall and I approached her, introduced myself and we just chopped it up for about a half hour. Didn't ask for her number or anything, (cause I was a pussy), but like I friend-ed her on Facebook.

Fast forward to today, I see her at the bar tending every weekend. I wan't to know is it even possible (appropriate) to try and strike up conversation? It's a college bar that is usually extremely loud and usually packed wall to wall until near the end of the night.

My overall question is should I even say anything? There is a possibility that she doesn't even remember me seeing that I've only talked about a half hour to her a few months ago. Any tips?
