Nothing is forever, and I do still talk about when I'll come back to Britain. I'd love to come back and do a nice big juicy period drama. I don't understand it when people suddenly turn their back on Britain or Scotland. I'm so aware of it, and it's so much a part of who I am.

I made some flippant remark about not wanting my son to grow up with an American accent, and the next thing I knew, there were people in America suggesting I head back to Britain if I was unhappy at such a prospect.

My husband is always telling me: 'We're on holiday - we don't need to have an itinerary!' But I always want to see as much as I can. Sometimes, I come back from holiday needing a holiday.

I don't even think places like the National Youth Theatre (NYT) are necessarily about wanting to be an actor when you grow up. They're about meeting people from different backgrounds and different religions and different cultures, and mixing with people that you wouldn't ordinarily meet.
