Should I say something? Would it be weird? Would it be too embarrassing for her? Would someone say "why were you looking?" To be fair, anyone standing where I stood, with a passing glance in that direction for any multitude of reasons would have seen exactly what I saw. I chose not to say anything, just enjoy that scene. I don't know the girl, but I've seen a part of her that few have ever seen. Wonder when she's going to start waxing?
