If there's a fire, a fire drill or a mysterious chlorine gas leak, it's vitally important you drop everything (except trousers) and rush outside. It might just save your life.
But only if you know where to stand. Brilliantly, the school puts everyone by the sports hall and gate. However, the old, currently dis-used car park has now got signs for Key Stage 3 forms there.
So what's the problem? They're the same signs used by the school to denote where to stand in a fire drill, fire or mysterious chlorine gas leak. So if you're in Key Stage 3, avoid the confusion: stay inside, stay inside and burn to death, be gassed.
