Just because you've played with matches or set a piece of paper alight doesn't mean your a pyro, your just a stupid kid. Back in my high school days we set fire to a pile of sticks/paper/flammable items (<.<, >.>) and could see the smoke pouring out so much we could see the smoke from school. We also had a tendency to spray deodorant heavily on our arms and hands and set them alight, good fun without water.
