The young person isn't certain that love can be real; the middle-aged man is only discovering that it is; and the older person seems so sure of it. I was interested in the way that many of us go through the whole of our lives staying with someone just out of complacency, because leaving isn't easy.

I have a theory about Ireland, being at the edge of Europe. For 1,000 years, people didn't know what was beyond. But we thought about it - a lot. And that 'beyond' became internalized in our psyche.

I guess I'm attracted and repelled by isolation. It scares me. And it's why I tend to write about older characters, too, because for them the stakes are somewhat higher.

I'm not a good storyteller - I much prefer to be with people who are chatty, to have the luxury of listening.

I'm living as an artist, and that's a staggering feeling, it's a total luxury. And because you have this amazing chance, with so much freedom, I'm determined to make something that is worth that. I feel this responsibility - to create something that makes an audience feel, which takes them somewhere. But that's very hard to achieve.
