People used to always ask, and I would say I wanted to be an actress. When they would ask why, I would say because my mother has so much fun.

You know what else I've learnt? That it's all right not to ride the crest of the wave. Every time a wave comes along I retreat, and I haven't come to any harm yet.

So much of my life is not about work and that is usually mainly what I do tweet about. We live a very quiet life.

My natural accent is American. I chose to speak with a U.K. accent when I was about to enter the final year at drama school in London. I was going to try to find a way to stay in the U.K. after I finished college and could not imagine trying to live and get work there with an American accent.

I started so slowly and had so few followers and then it kind of sort of snowballed. I still feel an intimacy on Twitter, which I think a lot of us do. It feels intimate, doesn't it? I love it. I never thought I would.

I distanced myself, relatively, from my parents for a year or so in my late twenties. It was necessary for me to feel my autonomy. Other than that brief gap, we have always been a very close family.

There is a cost that comes with moving schools so often and it's not what I want for my son when he gets older, but it did make me very adaptable. I became aware of what was missing from the social structure of each class that I arrived in, and made sure to fill that gap.
