Interesting Fact - Punctuation

New guidelines for school pupils in England state that only phrases starting with "what" or "how" merit an exclamation mark!

(This means that children who use punctuation marks in written tests will be penalised unless they adhere to strict rules.

I mean, I know I ask people not to use them in every sentence, and to stick to one, but really, this is way too prescriptive.

Irk the purists!)
