She knows, now, absolutely, hearing the white noise that is London, that Damien's theory of jet lag is correct: that her mortal soul is leagues behind her, being reeled in on some ghostly umbilical down the vanished wake of the plane that brought her here, hundreds of thousands of feet above the Atlantic. Souls can't move that quickly, and are left behind, and must be awaited, upon arrival, like lost luggage.

In effect, I grew up in a sort of timewarp, a place where times are scrambled up. There are elements of my childhood that look to me now, in memory more like the 1940s or the 1950s than the 1960s. Jack [Womack] says that that made us science fiction writers, because we grew up experiencing a kind of time travel.

When I start writing a new imaginary future, I have no idea what it is. The characters arrive first. They help me figure out where they are living and I get to fill in the gaps with that and where we are. So when I get to the end of the process of composition, if I feel that I have really done my job, I have no idea what I've got - and I then spend essentially the rest of my life figuring out what it might mean.

I'm interested in people who become culturally fluent. And when I meet young people I'm often amazed they don't quite seem to have a sense of where they're from. They're like the citizens of the airport.

When I come to a new city is I combine: I say, well, it's like Barcelona and Edinburgh, though I can't imagine what that would be. But Toronto, the last few times I've been here, what always comes up is Chicago and West Berlin. It's a big, sprawling city beside a lake, of a certain age and a certain architectural complexity. But the high-end retail core looks more like West Germany than the Magnificent Mile. Yonge Street is like K-Damm. There's an excess of surface marble and bronze: it's Germanic and as pretentious as pretentious can be.

I've gone to big stadium rock concerts at some artist's invitation, and there's this invariable, fascinating and rather sad situation of concentric circles of availability. There are Green Rooms within Green Rooms literally within Green Rooms. There are seven or eight degrees of exclusivity, and within each circle of exclusivity, everyone is so happy to be there, and they don't know that the next level exists.

I'm embarrassed if I think anyone knows exactly what I paid for something, or even where I got it. I want what I'm wearing to feel good on, wear well, and to be extremely functional.
