New York is great for writers insofar as you can pay someone to bring you food, to take your washing out and bring it back clean. It enables you. Writers always feel guilty when they're doing anything but writing, and New York allows you to really write all the time if you want to - though my kids put a limit on it.

Publishing a book is a great thing, and I'm grateful, but it's also a horrible, exposing thing. Once you've published a book, you never write quite as freely again. You're aware, from that point onward, of the kinds of things critics might say about it. You're aware of the kinds of things your publishers might like and dislike about it. You're half-aware of marketing strategies - of all the stuff around the book. Whereas with your very first piece of fiction, if you're lucky, those things barely occur to you at all.

Cargo cults fascinate me partly because Christianity itself is in many ways a cargo cult.

The reason that the book exists is because there was a gap in you. You wrote the book to fulfill that gap in some way.

There is such a shelter in each other.

That's what Samuel Johnson said: "Read over your compositions, and wherever you meet with a passage which you think particularly fine, strike it out."

With an age difference comes a great gap in cultural references, and so on. It's not all about race and gender. It interests me that, as you get older, your younger self becomes a stranger to you. A split occurs within yourself. But maybe we're all always strangers to ourselves.
