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.

The rule is: the word 'it's' (with apostrophe) stands for 'it is' or 'it has'. If the word does not stand for 'it is' or 'it has' then what you require is 'its'. This is extremely easy to grasp. Getting your itses mixed up is the greatest solecism in the world of punctuation. No matter that you have a PhD and have read all of Henry James twice. If you still persist in writing, 'Good food at it's best', you deserve to be struck by lightning, hacked up on the spot and buried in an unmarked grave.

Don't pessimism and caution naturally go hand in hand?

...when a phone call competes for attention with a real-world conversation, it wins. Everyone knows the distinctive high-and-dry feeling of being abandoned for a phone call, and of having to compensate - with quite elaborate behaviours = for the sudden half-disappearance of the person we were just speaking to. 'Go ahead!' we say. 'Don't mind us! Oh look, here's a magazine I can read!' When the call is over, other rituals come into play, to minimise the disruption caused and to restore good feeling.

I recently heard of someone studying the ellipsis (or three dots) for a PhD. And, I have to say, I was horrified. The ellipsis is the black hole of the punctuation universe, surely, into which no right-minded person would willingly be sucked, for three years, with no guarantee of a job at the end.

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.

You should read Wodehouse when you're well and when you're poorly;when you're travelling, and when you're not;when you're feeling clever, and when you're feeling utterly dim. Wodehouse always lifts your spirits,no matter how high they happen to be already.
