When I was 12 I was riding in the train home from my very first day of high school. I was really happy and had lots of fun that first day. The train wasn't busy, but it was far from empty, and I was seated in a 4 person area, since that was the only place at the moment where nobody was sitting. Until a first year college student came sitting across from me and started talking to me. He was really friendly and asked me about my day, told me it was his first day of college too. We made small talk and had quite a bit of fun for the 10 minute train ride to my hometown. Turned out he lived there too. And what happened next is something that is the weirdest, most brazen and creepiest thing that ever happened to me. He got up and walked behind me towards the exit of the train, when I heard him whisper in my ear something like "want to come over to my house to hang out? I have a PS3." and I swear he touched my butt when he said it, although come to think of it, it might have been his bag or something. In front of dozens of passengers. I got out of the train, ran to my bike and raced home as fast as I could. Fun fact: this event was one of the main contributing factors to make me realize that I was gay one or two years later. I haven't told anyone this before, you guys are the first.
