But in life you have to take lots of decisions and if you don't take decisions you would never do anything because you would spend all your time choosing between things you could do. So it is good to have a reason why you hate some things and you like others.

Siobhan said that when you are writing a book you have to include some descriptions of things. I said that I could take photographs and put them in the book. But she said the idea of a book was to describe things using words so that people could read them and make a picture in their own head.

And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.

My book has a very simple surface, but there are layers of irony and paradox all the way through it.

Stories about mental aberration and oddity only make sense in context. Just how do people live with someone who is peculiar, gifted, strange or alien?
