I think airports are places of huge human drama. The more I see of it, the more I am convinced that Heathrow is a secret city, with its own history, folklore and mythology. But what has surprised me is the love the people who work there feel for the place. Everyone seems to think they are plugged into something majestic.

Largely this is a class thing - writers tend to be cosseted little middle-class kiddies who think that the world owes them a royalty cheque. But just doing it - being in your room for years on end, locked in your head, alone with invented ghosts - it weakens and softens the body. And I know I can't just live in my head.

I feel like the only person in the world who sees David Beckham modelling his swimming pants on the cover of Elle magazine and thinks - oh, how much better a handsome guy like you would look, David, without all those dumb ink stains stitched into your skin.

I do tend to look back to my parents generation and think wow! what a great way to be, to live with one person for a lifetime, to bring your kids up in these really solid families.

I can't think of a bigger waste of police time than chasing somebody who has said something offensive on Twitter.

I don't think much of anything I wrote before the age of 30.
