So I live in a large town/small city (depending on which way you look at it).
Well I was walking into the restaurant I was going to have lunch at and I bump into a guy I used to date in college. I am wearing my big sunglasses, notice him out of the corner of my eye and think "sh!t! please don't see me, please don't see me". Well he does see me but he's w/clients. I think "please don't talk to me, please don't talk to me". Well he does. He gave be a quick hug and "nice to see you". It was akward - if I could turn red, i would have been all sorts of red!
Well don't you know by the time I got our table he had texted me! I had to let him know I was married, but it was still flattering!
