When I was a youngster my pal and I got on our bikes and just rode. It was several hours before we realised that we didn't have a clue where we were or more importantly, how to get home again. My parents always told me that if I was in trouble, ask a policeman. I do not remember much about the journey home because I fell asleep in the back of a police car, but I certainly got a good talking to when I got home.
