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

Well, start waving and yelling, because it is the so-called Oxford comma and it is a lot more dangerous than its exclusive, ivory-tower moniker might suggest. There are people who embrace the Oxford comma and people who don't, and I'll just say this: never get between these people when drink has been taken. Oh, the Oxford comma. Here, in case you don't know what it is yet, is the perennial example, as espoused by Harold Ross: "The flag is red, white, and blue." So what do you think of it? Are you for or against it? Do you hover in between?

Many aspects of our screen-bound lives are bad for our social skills simply because we get accustomed to controlling the information that comes in, managing our relationships electronically, deleting stuff that doesn't interest us. We edit the world; we select from menus; we pick and choose; our social 'group' focuses on us and disintegrates without us. This makes it rather confusing for us when we step outdoors and discover that other people's behaviour can't be deleted with a simple one-stroke command or dragged to the trash icon.

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.

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

As someone who sends texts messages more or less non-stop, I enjoy one particular aspect of texting more than anything else: that it is possible to sit in a crowded railway carriage laboriously spelling out quite long words in full, and using an enormous amount of punctuation, without anyone being aware of how outrageously subversive I am being.

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.
