Well in this case, all I can say is that I am sure not ALL me would be noticing you (I am sure they have their own drinks/dates/partners/pool tables/football games to keep them busy). A couple of them, sure its a possibility they may be eyeing whats happening. But then who cares. And if they happen to be laughing, its just because its human nature! Let them have their laugh, but I for one wouldn't take it so personally.
