Proper punctuation is both the sign and the cause of clear thinking.

The problem is that it has become politically awkward to draw attention to absolutes of bad and good. In place of manners, we now have doctrines of political correctness, against which one offends at one's peril: by means of a considerable circular logic, such offences mark you as reactionary and therefore a bad person. Therefore if you say people are bad, you are bad.

In my worst moments, I think the biggest effect of 'Eats, Shoots & Leaves' was to kill the happiness of people who had previously skipped through life, unaware of all the atrocities lurking in the world around them.

A Panda walks into a cafe. He orders a sandwich, eats it, then draws a gun and fires two shots into the air. "Why?" asks the confused waiter, as the panda makes toward the exit. The panda produces a badly punctuated wildlife annual and tosses it over his shoulder. "I'm a Panda," he says, at the door. "Look it up." The waiter turns to the relevant entry, and, sure enough, finds an explanation. Panda. Large black and white bear-like mammal, native to China. Eats, shoots and leaves.

After university, I got a job sub-editing and for years I was a literary editor.

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.

Punctuation marks are the traffic signals of language: they tell us to slow down, notice this, take a detour, and stop.
