I've been writing full-time since I was 23.

The idea was to focus on the primal drama of parenthood: the way from moment to moment you swing from comforter to tormentor, just as kids simultaneously light up our lives and drive us nuts. I was trying to capture that strange, bipolar quality of parenthood. For all that being a parent is normal statistically, it's not normal psychologically. It produces some of the most extreme emotions you'll ever have.

I really like to keep my palette small but to be very intense, very myopic.

Writing stories is my way of scratching that itch: my escape from the claustrophobia of individuality. It lets me, at least for a while, live more than one life, walk more than one path. Reading, of course, can do the same.

If you have written something that the film people want, like a book, it does give you a way in.

What writing ROOM taught me was that I know exactly how to be the perfect mother, but I'm not willing to do it for more than ten minutes at a time.

The Collector [John Fowles book] does such a good job of capturing the mindset of a capturer, and also that's become a banal trope of every second crime novel: the weirdo, fetishistic watcher/stalker/kidnapper/kidnapper of women or children.
