One day a few years ago, I was at the local skatepark, which happens to have a fine view of the tracks. I was doing fine until some guy decides to annoy me by throwing rocks at the train. I call the police, and he gets taken away.
Now for the odd part. I started talking to him a year later about something else, having no idea this is the guy I called the cops on. When I realized who he was, I thought it was pretty funny. Now he's my bass player/ drummer (I play guitar) and we are good friends.
