WW, I can relate to those feelings. Wonder if I will ever feel confident enough to approach someone who appeals to me instead of waiting, waiting, waiting ...At a folk festival by a lecherous (I thought) bodhran player at least 10 years older "You're gorgeous, want a beer?" I accepted the beer of course but declined his request for my phone number.
Also, I have had the "Are you a model?" one. Bleuch.
