I’m a 13 year old girl and was at the library. This man was looking in the teenage fiction section alone. He was mostly behind me, with his hands on his back. I swear I could feel something, like someone touching my butt in a subtle way? I didn’t say anything to my mom at all because I’m not gonna accuse people like that even though when I turned around, it almost looks like he is. He randomly started talking to me and introduced himself , then asked for my name. At first, I didn’t respond to him but he asked again. I didn’t wanna be rude so I said my first name.
