I work in the library music department, and there is this one gorgeous girl who comes in every once in awhile. I've helped her a few times before and shes always seemed grateful. Last night I saw her at one of the bars off campus. I approached and asked her if she was the girl from the library, she smiled and said yes. Then I asked her if she would like to dance. Instantly rejected. Do you guys have any advise on what to do in this situation. Should I offer to buy her a drink first?
