The advent of the mobile phone was a disaster. We are forced to listen, open-mouthed, to other people's intimate conversations. Increasingly, we are all in our virtual bubbles when we are out in public, whether we are texting, listening to iPods, reading or just staring dangerously at other people.

Evidently an A level in English is a sacred trust, like something out of "The Lord of the Rings". You must go forth with your A level and protect the English language with your bow of elfin gold.

I am not against marriage. I lived with someone for 11 years. But we weren't in love, and I thought that was quite important.

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.

We have a language that is full of ambiguities; we have a way of expressing ourselves that is often complex and elusive, poetic and modulated; all our thoughts can be rendered with absolute clarity if we bother to put the right dots and squiggles between the words in the right places. Proper punctuation is both the sign and the cause of clear thinking. If it goes, the degree of intellectual impoverishment we face is unimaginable.

To those who care about punctuation, a sentence such as "Thank God its Friday" (without the apostrophe) rouses feelings not only of despair but of violence. The confusion of the possessive "its" (no apostrophe) with the contractive "it's" (with apostrophe) is an unequivocal signal of illiteracy and sets off a Pavlovian "kill" response in the average stickler.
