To those who care about punctuation, a sentence such as "Thank God its Friday" (without the apostrophe) rouses feelings not only of despair but of violence. The confusion of the possessive "its" (no apostrophe) with the contractive "it's" (with apostrophe) is an unequivocal signal of illiteracy and sets off a Pavlovian "kill" response in the average stickler.

All writers learn this, in time: don't show your work to other people until it's safely finished. Even discussing your unborn book in quite general terms can be such an undermining experience that, afterwards, you give it up and go to live in Guatemala.

The reason to stand up for punctuation is that without it there is no reliable way of communicating meaning.

The idea of withholding a massive secret is obviously quite exciting to some people. It is also the basis of much classic drama, of course, from Sophocles onwards.

Manners are about imagination, ultimately. They are about imagining being the other person.

I used to help my dad with a stall selling eggs when I was about 12. People were so hard up they would ask for one egg. But mostly no one came by at all. It was very demoralising.

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.
