And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don’t even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don’t have to take them into account when you are calculating something.

There was a time in my life when I was going in and out of houses that were extraordinarily different - from a working-class terrace in Northampton to the homes of friends who were really very wealthy. It was quite an odd position to be in, I realise looking back, and quite a nice one.

And then I thought that I had to be like Sherlock Holmes and I had to detach my mind at will to a remarkable degree so that I did not notice how much it was hurting inside my head.

Curious Incident is not a book about asperger's....if anything it's a novel about difference, about being an outsider, about seeing the world in a surprising and revealing way. The book is not specifically about any specific disorder.

One person looks around and sees a universe created by a god who watches over its long unfurling, marking the fall of sparrows and listening to the prayers of his finest creation. Another person believes that life, in all its baroque complexity, is a chemical aberration that will briefly decorate the surface of a ball of rock spinning somewhere among a billion galaxies. And the two of them could talk for hours and find no great difference between one another, for neither set of beliefs make us kinder or wiser.

Madness doesn't happen to someone alone. Very few people have experiences that are theirs alone.

I do not like strangers because I do not like people I have never met before. They are hard to understand.
