I remember being on after-school homework/detention duty a few years ago. It was on the second story of a building to separate it from the rest of the school. The time had started and the students had spread themselves around and were getting on with their work, when out of the lift came three students, one of whom was riding a scooter. Can I just say, the seriousness and control that was in that space quickly dissipated, turning into chaos. It was interesting to see other students initially laugh, until it stopped being funny.
