Some youngsters don't have paper to draw on and they draw everywhere else. Once I saw a nice looking young man doing graffiti on the outer wall of a commuter train. I felt the smell of the paint and looked out of the window. I had no camera with me and my phone was at home. There was no crew in the compartment and the train just started towards Kerava. So I could not turn him in. I should have if I had been able to.
