Dear Mr and Mrs Biggins,
I regret to inform you that some boys have set fire to their form tutor’s hair here at Cox Academy. We suspect your son’s among the culprits. This was done with one of the Science Department’s magnifying glasses on an unusually hot day. Mr Bibby’s flaming orange locks won’t be the same again. Let’s meet up to discuss this as soon as possible. I hope you’ll agree that this action’s got to be punished.

Yours sincerely,
Mr Cox,
Headmaster.

Dear parents,
As you know, we are taking the boys on a trip to the mountains in France where we hope to explore the local environment including some exciting rock formations. It’s going to be incredibly hot so your son’s going to need:
sturdy, unfashionable boots;
thermal underpants;
itchy trousers;
tins of beans and sausages;
dynamite;
a spoon.
It’s very important that you send back the reply form with your son first thing on Monday as we depart in the first week of the Summer Term.

Yours sincerely,
Mr Cox,
Headmaster.
