It's never much fun at school - it's just dates. Then as you get older, for some reason, you get more interested.

You hope people won't be tricky or miserable. If you're in public life, it's important not to be. If someone says, 'I like your programme, thank you,' you should be grateful. I am. Why be nasty?

Georgian England, to see those wonderful houses being built. And the clothes were interesting too, although I wouldn't want to wear a wig. It's also the most beautiful period of English landscape gardening. They had famous gardeners like Capability Brown.

Once I was on a plane and a woman said to me, 'Now, what's the matter with my tomatoes?' And I said, 'Well, it's a bit difficult to see from here.' She took offence and said, 'I was only trying to be friendly.'

I never get bored of my wife. It's lovely.

Airports - they're not my idea of fun at all. Some of the staff are lovely, but you do always get one or two that seem to forget that it's actually costing you a lot of money to be there and be insulted by their surliness. Times have obviously changed and we need to get used to being more strictly vetted, but they could be more pleasant about it. A smile wouldn't go amiss.

Julia Roberts was really rather lovely. I had to interview her on Pebble Mill At One years ago. You learn not to be starstruck if you're trying to get a decent interview out of someone. If you fall apart it's counter productive.
