I think that's what's great about being an actress is you get to learn so many different things like that, like learning a little bit of Tibetan here, learning a Southern accent there.
I used to love to play dress-up, where you get your mother's or your grandmother's dresses and high heels.
I don't think people who have children are acting selfishly or unselfishly. Having a child who'll be loved, to parents who love each other, is the important thing.
