When I was a teenager usually we used to do (me and my friends) some things messing about, but not things so dangerous as the South London teenagers history.
Usually we broke in an old house, where nobody lived in. The neighbours always were hungry because they listened to a not common noises, and they thought that it was a very dangerous activity for us. MAybe they have a real reason, but ... we were a teenagers!!!
One day, the neighbours called the police. And...what a scare! My god!! I don't forget these day for the rest of my life.
