Nobody ever forgets their first night in the bush. It's among the precious, meagre handful of life firsts that remain indelible.

Is it a particularly British trait to so utterly adore truly appalling men, from Tony Hancock through to Steptoe and Alf Garnett, Captain Mainwaring, Rigsby, Del Boy, Victor Meldrew and on to David Brent from The Office. The most deeply adored characters are all simply vile.

Celebrity is a national drama whose characters' parts and plots are written by the tabloids, gossip columnists, websites and interactive buttons. The famous don't actually have to turn up to their own lives at all.

Get up now and go and find Robert Kilroy-Silk. Smile in a warm, friendly sort of way, then punch him on the nose. Now go and find Robert on television, despite my best endeavours, this is still relatively easy to do. Wait for a close-up, same smile, and punch him on the nose. If you followed the instructions carefully, you will have noticed a distinct difference. On the one hand, you were suffused with a sense of public-spirited righteousness; on the other, you're probably dribbling blood. That's the difference between reality in life and reality on television.

There were moments when I wondered at the gossamer veil that stops licence from being libel. I suspect that taking on the job of England manager puts you outside the protection of the courts.
