As I say, I have never in all these years thought of the matter in quite this way; but then it is perhaps in the nature of coming away on a trip such as this that one is prompted towards such surprising new perspectives on topics one imagined one had long ago thought throughly.

After all, what can we ever gain in forever looking back and blaming ourselves if our lives have not turned out quite as we might have wished?

If you go to Tokyo, I think it becomes very obvious that there's this almost seamless mixture of popular culture and Japanese traditional culture.

All I know is that I've wasted all these years looking for something, a sort of trophy I'd get only if I really, really did enough to deserve it. But I don't want it anymore, I want something else now, something warm and sheltering, something I can turn to, regardless of what I do, regardless of who I become. Something that will just be there, always, like tomorrow's sky. That's what I want now, and I think it's what you should want too. But it will be too late soon. We'll become too set to change. If we don't take our chance now, another may never come for either of us.

So why not become a mongrel? It's healthy

Throughout my career I've struggled to encourage people to read my books on a more metaphorical level. I'm less attached to my settings than, for example, Saul Bellow. The setting of a novel for me is just a part of the technique. I choose it at the end.

I still have a suspicion of charity and think the state has a role to play in many areas. And although for most of the years since I have been a rather privileged writer, I identify more closely than perhaps I should with those social workers. Had I not become a writer that would have been me. Lots of our friends are still in that world and I do feel part of that generation of people who were rather idealistic in the 70s and became disillusioned in the 80s. Not just about social services issues, but the world.
