A couple of years ago, I was standing on a station platform, waiting for a train to head home after finishing university for the day. A girl around my age approached me. She stood uncomfortably close right in front of me, leaned in, and whispered in my ear; “dude, your fly is completely open. I’m standing here so you can fix it without anyone seeing.” After promptly slamming shut the ol’ dick-door, we shared a laugh (mine obviously slightly more nervous/embarrassed ,) and then ended up getting on the same train. We had a very in-depth discussion about subjects we were both studying like literature and philosophy (fuck that sounds so douchey, r/iamverysmart anyone?) We were both, however, using the train as a connecting service, so we got off on different stops and went in opposite directions. Neither of us thought to ask the other for Facebook accounts or anything. I wasn’t “interested” or anything, I’m happily taken, but she just seemed like a really funny and interesting person who I would have liked to become friends with.
