My pen.’ Funny, I wrote that without noticing. ‘The torch’, ‘the paper’, but ‘my pen’. That shows what writing means to me, I guess. My pen is a pipe from my heart to the paper. It’s about the most important thing I own.

The dreams now were simply of staying alive.

It all began when... they're funny, those words. Everyone uses them, without thinking what they mean. When does anything begin? With everyone it begins when you're born. Or before that, when your parents got married. Or before that, when your parents were born. Or when your ancestors colonised the place. Or when humans came squishing out of the mud and slime, dropped off their flippers and fins, and started to walk. But all the same, all that aside, for what's happened to us there was quite a definite beginning

If you added up all the really significant episodes in your life they'd probably come to less than sixty minutes.

So I found myself telling my own stories. It was strange: as I did it I realised how much we get shaped by our stories. It's like the stories of our lives make us the people we are. If someone had no stories, they wouldn't be human, wouldn't exist. And if my stories had been different I wouldn't be the person I am.

Life's about a hell of a lot more than being happy. It's about feeling the full range of stuff: happiness, sadness, anger, grief, love, hate. If you try to shut one of those off, you shut them all off. I don't want to be happy. I know I won't live happily ever after. I want more than that, something richer. I want to go right up close to the beauty and the ugliness. I want to see it all, know it all, understand it all. The richness and the powerty, the joy and the cruelty, the sweetness and the sadness. That's the best way I can honour my friends who died.

We'd thought that we were among the first humans to invade this basin, but humans had invaded everything, everywhere. They didn't have to walk into a place to invade it.
