One thing lots of Christians do have in common is that they can't help coming across as smug. This winds lots of people up, particularly because famous Christians pronounce on the life of the poor from their very lovely affluent homes filled with their very lovely families and attractive pets.

I think there's a far more general audience now because I've done more populist stuff on telly.

How do you conduct an intimate relationship where no one ever loses it? Where no one ever lashes out, where no one ever smacks anyone in the mouth?

I just don't like travelling very much.

I do say no to lots of things, actually! I know it doesn't look like it. But I have a tendency to a) be rubbish at saying no, and b) be pushed by some kind of Protestant work ethic.

My mum and my husband are from Irish backgrounds so we have a lot of potatoes. Chips, mashed, boiled, new potatoes, I love them all. Even the slightly wanky ones like Duchess potatoes that go up in a little spiral.

And I also felt that no one in an audience could abuse me worse than the sort of abuse I had had at work as a psychiatric nurse.
