Don't touch my thigh.
I'm new at my job. I was standing around doing something at a counter. This co-worker, who I had NEVER met before, randomly walked over to me and plucked a thread off of my pants. The thread was located mid-thigh. Then he walked away. This situation was especially weird because this guy's double my age.
I mentioned this to my supervisor, who is about my age, and she didn't really sympathize. I asked her if he was a creep, and she said, "no, he's a really good guy, such a good guy, he's married and has a kid."
Oh really? Great, because for a second there I thought he was a jerk.
