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.

Why did the Apostrophe Protection Society not have a militant wing? Could I start one? Where do you get balaclavas?

The rule is: don’t use commas like a stupid person. I mean it.

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.

Truly good manners are invisible: they ease the way for others, without drawing attention to themselves. It is no accident that the word "punctilious" ("attentive to formality or etiquette") comes from the same original root as punctuation.

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

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.
