In the family of punctuation, where the full stop is daddy and the comma is mummy, and the semicolon quietly practises the piano with crossed hands, the exclamation mark is the big attention-deficit brother who gets overexcited and breaks things and laughs too loudly.

Offence is so easily given. And where the 'minority' issue is involved, the rules seem to shift about: most of the time a person who is female/black/disabled/gay wants this not to be their defining characteristic; you are supposed to be blind to it. But then, on other occasions, you are supposed to observe special sensitivity, or show special respect.

Sticklers never read a book without a pencil at hand, to correct the typographical errors. In short, we are unattractive know-all obsessives who get things out of proportion and are in continual peril of being disowned by our exasperated families.

My favorite thing in the world is a quiz show, 'University Challenge,' so you can see what kind of sad person I am.

I mean, full stops are quite important, aren't they? Yet by contrast to the versatile apostrophe, they are stolid little chaps, to say the least. In fact one might dare to say that while the full stop is the lumpen male of the punctuation world (do one job at a time; do it well; forget about it instantly), the apostrophe is the frantically multi-tasking female, dotting hither and yon, and succumbing to burn-out from all the thankless effort.

What one discovers in life, I find, is that one's personality defects don't come and go.

For any true stickler, you see, the sight of the plural word “Book’s” with an apostrophe in it will trigger a ghastly private emotional process similar to the stages of bereavement, though greatly accelerated. First there is shock. Within seconds, shock gives way to disbelief, disbelief to pain, and pain to anger. Finally (and this is where the analogy breaks down), anger gives way to a righteous urge to perpetrate an act of criminal damage with the aid of a permanent marker.
