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 say "on principle" [regarding 'lesbian writer'] because whenever you get one of your minority labels applied, like "Irish Writer," "Canadian Writer," "Woman Writer," "Lesbian Writer" - any of those categories - you always slightly wince because you're afraid that people will think that means you're only going to write about Canada or Ireland, you know.

I always wince a little bit when I send me to each of my new books. I wince at submitting myself to my father's judgment. But, of course, he's such a fond father that he always writes back, saying it's the greatest thing ever written.

I needed to do a lot of saying no. I had a lot of [interest] from people who I just didn't think were quite right for it. And I didn't want a bad film to be made of the book, either a sentimental one or a creepy one, so I did a lot of, "No thank you." Then when the right filmmaker came along, yes, I suppose I presented myself very much as wanting to be the writer.

There are so many examples today of how the kind of wonderful zealousness and unquestioning loyalty of young people can be harnessed by all sorts of insidious powers.

I must say, in the case of "Room," both the book and the film, I don't think being a lesbian author held me back at all.

People are locked up in all sorts of ways.
