One halloween in college I dressed as a girl, but left the facial hair so as not to do "too good" of a job (My first time dressed in public, still in the closet otherwise). We went to the college bar, and we're having a great time, and when I went up to the bar to get another pitcher of beer, someone comes up behind me and says "Hey good lookin', can I buy you a drink?". So I turn around, and it's one of my classmates! He was pretty drunk, but it only took a second or two for his face to go from drunken smile, to confused, to shocked.

At this point I began to worry that I may become involved in bar violence, but then he laughed and said "I'm so sorry man, I had no idea...you did a good job!". So we laughed and chatted about school stuff for a bit, and the night eventually ended without incident.

Anyway, even if it was from behind, on halloween, in a bar, it still had me on cloud nine that I was hit-on, and I'm not even attracted to guys. I had ultra-confidence for the rest of the night. :D
