I said that when Father got up in the morning he always put his trousers on before he put his socks on and it wasn’t logical but he always did it that way, because he liked things in a nice order, too. Also whenever he went upstairs he went up two at a time, always starting with his right foot.

Mr. Jeavons said that I was a very clever boy.

I said that I wasn’t clever. I was just noticing how things were, and that wasn’t clever. That was just being observant. Being clever was when you looked at how things were and used the evidence to work out something new. Like the universe expanding, or who committed a murder. Or if you see someone’s name and you give each letter a value from 1 to 26 (a = 1, b = 2, etc.) and you add the numbers up in your head and you find that it makes a prime number, like Jesus Christ (151), or Scooby-Doo (113), or Sherlock Holmes (163), or Doctor Watson (167).

Mr. Jeavons asked me whether this made me feel safe, having things always in a nice order, and I said it did.

Then he asked if I didn’t like things changing. And I said I wouldn’t mind things changing if I became an astronaut, for example, which is one of the biggest changes you can imagine, apart from becoming a girl or dying.

He asked whether I wanted to become an astronaut and I said I did.

He said that it was very difficult to become an astronaut. I said that I knew. You had to become an officer in the air force and you had to take lots of orders and be prepared to kill other human beings, and I couldn’t take orders. Also I didn’t have 20/20 vision, which you needed to be a pilot. But I said that you could still want something that is very unlikely to happen.

Terry, who is the older brother of Francis, who is at the school, said I would only ever get a job collecting supermarket trollies or cleaning out donkey shit at an animal sanctuary and they didn’t let spazzers drive rockets that cost billions of pounds.
