I've worn thongs since I was 13. This story is about a time when I was 16. I forget the name of the store, but I was shopping at the mall in a clothing store. I went to try something on, and I was a bit surprised that there weren't actually changing "rooms." There was a hall that had little cubicles with curtains to cover the entrance. There were no doors, and as such, there were no locks. I was trying on a pair of jeans, and I took off my pants. Just as I was bending over to step into the jeans, a young guy about 20 pulls back the curtain. He wasn't paying attention and didn't see that I was in there until it was too late. We were both caught off guard, and he replaced the curtain and apologized from the other side. It was mostly embarrassing for me because I was bent over at the time, otherwise I might not have minded. Now that I'm a couple years older, I don't think I would have minded at all.
