Here's something else you'd probably better not do today. I suspect the incident didn't actually resemble a Hollywood kidnapping, with screaming, threats and an entire roll of gaffa tape, but was probably a gentle and harmless bit of fun. It was nothing more than a light hearted way of trying to remind the children to sit quietly and listen. (Which is doubtless frowned upon nowadays anyway)
Needless to say the reaction is hysterical and you can already see one of the parents angling for the 'allergy' angle. No doubt 'trauma and distress' will soon follow, which can only be soothed by a large out of court settlement.
I have just come off the phone to my parents and we are preparing our own legal battle for justice over a similarly brutal event that has traumatised me since 1972. I knew education would make me rich somehow.
