“A lie is when you say something happened which didn't happen. But there is only ever one thing which happened at a particular time and a particular place. And there are an infinite number of things which didn't happen at that time and that place. And if I think about something which didn't happen I start thinking about all the other things which didn't happen.For example, this morning for breakfast I had Ready Brek and some hot raspberry milkshake. But if I say that I actually had Shreddies and a mug of tea I start thinking about Coco-Pops and lemonade and Porridge and Dr Pepper and how I wasn't eating my breakfast in Egypt and there wasn't a rhinoceros in the room and Father wasn't wearing a diving suit and so on and even writing this makes me feel shaky and scared, like I do when I'm standing on the top of a very tall building and there are thousands of houses and cars and people below me and my head is so full of all these things that I'm afraid that I'm going to forget to stand up straight and hang onto the rail and I'm going to fall over and be killed.This is another reason why I don't like proper novels, because they are lies about things which didn't happen and they make me feel shaky and scared.And this is why everything I have written here is true.”

“And it's best if you know a good thing is going to happen, like an eclipse or getting a microscope for Christmas. And it's bad if you know a bad thing is going to happen, like having a filling or going to France. But I think it is worst if you don't know whether it is a good thing or a bad thing which is going to happen.”

“Also I didn't have 20/20 vision which you needed to be a pilot. But I said you could still want something that is very unlikely to happen.”

“And Siobhan says people go on holidays to see new things and relax, but it wouldn’t make me relaxed and you can see new things by looking at earth under a microscope or drawing the shape of the solid made when 3 circular rods of equal thickness intersect at right angles. And I think that there are so many things just in one house that it would take years to think about all of them properly. And also, a thing is interesting because of thinking about it and not because of it being new.”

“When people die they are sometimes put into coffins, which means that they don't mix with the earth for a very long time until the wood of the coffin rots. But Mother was cremated. This means that she was put into a coffin and burned and ground up and turned into ash and smoke. I do not know what happens to the ash and I couldn't ask at the creamatorium because I didn't go to the funeral. But the smoke goes out of the chimney and into the air and sometimes I look up and I think that there are molecules of Mother up there, or in clouds over Africa or the Antarctic, or coming down as rain in the rain forests in Brazil, or snow somewhere.”

“When I arrived at Oakhill, I didn't think I was that far gone. I didn't think that the screw inside my head was that loose. But it is. And there isn't a screwdriver around anywhere to tighten it. I’m sure I had all my screws when I came here. But this place…This place will take things from you.This place makes the sane people crazy and the slightly crazy people insane.I start questioning myself.I start repeating, Is that what happened to me?”

“Between the roof of the shed and the big plant that hangs over the fence from the house next door I could see the constellation Orion. People say that Orion is called Orion because Orion was a hunter and the constellation looks like a hunter with a club and a bow and arrow, like this:But this is really silly because it is just stars, and you could join up the dots in any way you wanted, and you could make it look like a lady with an umbrella who is waving, or the coffeemaker which Mrs. Shears has, which is from Italy, with a handle and steam coming out, or like a dinosaur. And there aren't any lines in space, so you could join bits of Orion to bits of Lepus or Taurus or Gemini and say that they were a constellation called the Bunch of Grapes or Jesus or the Bicycle (except that they didn't have bicycles in Roman and Greek times, which was when they called Orion Orion). And anyway, Orion is not a hunter or a coffeemaker or a dinosaur. It is just Betelgeuse and Bellatrix and Alnilam and Rigel and 17 other stars I don't know the names of. And they are nuclear explosions billions of miles away. And that is the truth. I stayed awake until 5:47. That was the last time I looked at my watch before I fell asleep. It has a luminous face and lights up if you press a button, so I could read it in the dark. I was cold and I was frightened Father might come out and find me. But I felt safer in the garden because I was hidden. I looked at the sky a lot. I like looking up at the sky in the garden at night. In summer I sometimes come outside at night with my torch and my planisphere, which is two circles of plastic with a pin through the middle. And on the bottom is a map of the sky and on top is an aperture which is an opening shaped in a parabola and you turn it round to see a map of the sky that you can see on that day of the year from the latitude 51.5° north, which is the latitude that Swindon is on, because the largest bit of the sky is always on the other side of the earth. 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 your life it is nice to think that they are what is called negligible, which means that they are so small you don't have to take them into account when you are calculating something. I didn't sleep very well because of the cold and because the ground was very bumpy and pointy underneath me and because Toby was scratching in his cage a lot. But when I woke up properly it was dawn and the sky was all orange and blue and purple and I could hear birds singing, which is called the Dawn Chorus. And I stayed where I was for another 2 hours and 32 minutes, and then I heard Father come into the garden and call out, "Christopher...? Christopher...?”
