Mark Haddon said this quote
“ And when I am in a new place, because I see everything, it is like when a computer is doing too many things at the same time and the central processor unit is blocked up and there isn't any space left to think about other things. And when I am in a new place and there are lots of people there it is even harder because people are not like cows and flowers and grass and they can talk to you and do things that you don't expect, so you have to notice everything that is in the place, and also you have to notice things that might happen as well. And sometimes when I am in a new place and there are lots of people there it is like a computer crashing and I have to close my eyes and put my hands over my ears and groan, which is like pressing CTRL + ALT + DEL and shutting down programs and turning the computer off and rebooting so that I can remember what I am doing and where I am meant to be going. ”
