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

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.

I mean, full stops are quite important, aren't they? Yet by contrast to the versatile apostrophe, they are stolid little chaps, to say the least. In fact one might dare to say that while the full stop is the lumpen male of the punctuation world (do one job at a time; do it well; forget about it instantly), the apostrophe is the frantically multi-tasking female, dotting hither and yon, and succumbing to burn-out from all the thankless effort.

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.

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.

...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.

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