Life is deeply tragic and also very comic at the same time. It's everything at once.

It's like a mathematical law, Grace.

I've been asked several times over the years to become president, and I've always said no, because I didn't want to give up all the time from my work. The position won't be open for another year, but if they still want me then, I'll do it; I'll speak out as often as I can from that platform.

My wife is my first reader, my first line of defence I suppose. So she says, "Oh well, oh yes, it's all true." At the same time, I could have written much more about us, but I didn't want to go any further. I did cut things out. There are certain things that I wrote about her that are so gushing with praise and admiration that when I looked at those passages I realised they would be ridiculous to anybody else.

I never would have thought of that word, "hospitality." I settle into the rhythm of my steps.

Guilt kept me going. It was impossible not to blame myself for what had happened, but even guilt was a comfort. It was a human feeling, a sign that I was still attached to the same world that other men lived in.

I don't know why I write. If I knew the answer, I probably wouldn't have to. But it is a compulsion. You don't choose it, it chooses you. And I wouldn't recommend it to anybody.
