Punctuation is a courtesy designed to help readers to understand a story without stumbling.

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

I recently heard of someone studying the ellipsis (or three dots) for a PhD. And, I have to say, I was horrified. The ellipsis is the black hole of the punctuation universe, surely, into which no right-minded person would willingly be sucked, for three years, with no guarantee of a job at the end.

Texting is a supremely secretive medium of communication - it's like passing a note - and this means we should be very careful what we use it for.

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?

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.

As with email, the recipient of a texted question seems to have the option to ignore it, while nevertheless saying hello, lovely day, and so on.
