Note to all Heads. Next time a teacher comes into your office and says something along the lines of:
"I know, why don't we pretend to have been beaten up by robbers one morning next week to frighten the kids. I've got some fake blood from the joke shop and there's loads of bandages left in the first aid kit. Jim's got a mate who's a copper and they can come round, put up some of that stripey tape they use on the telly and pretend to investigate... it'll be a great laugh and we can call it 'Didactic Learning' or something daft! Go on, can we?"
It's probably best to say "No!"
