I can remember saying again and again and again, "A terrible thing has happened, but this should be a kind of wake-up call for our country, and we have a great opportunity now to reinvent ourselves. To rethink our position about oil and energy, to rethink our relationship with other cultures and other countries, and why other people want to attack us."

I've dealt with numbers all my life, of course, and after a while you begin to feel that each number has a personality of its own. A twelve is very different from a thirteen, for example. Twelve is upright, conscientious, intelligent, whereas thirteen is a loner, a shady character who won't think twice about breaking the law to get what he wants. Eleven is tough, an outdoorsman who likes tramping through woods and scaling mountains; ten is rather simpleminded, a bland figure who always does what he's told; nine is deep and mystical, a Buddha of contemplation.

Memory and the imagination are almost identical. It's the same place in the brain and the same thing is happening. When you think about your own life, there are no memories without place. You are always situated somewhere. I think the imagination - the narrative imagination at least - situates you in a specific space when you start to think of a story. I often use places I know. I put my characters inside rooms and houses that I'm familiar with - sometimes the houses of my parents or grandparents or previous apartments I've lived in.

At that point, Noriko finally breaks down and begins to cry sobbing into her hands as the floodgates open - this young woman who has suffered in silence for so long, this good woman who refuse to believe she's good, for only the good doubt their own goodness, which is what makes them good in the first place. The bad know they are good, but the good know nothing. They spend their lives forgiving others, but they can't forgive themselves.

When you're young, you keep reading new writers and you keep changing your mind about how you ought to sound.
