The Curious Incident of the Dog at the night-time

Prime numbers are what is left when you have taken all the patters away. I think prime number are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them.

[...] Because it is sort of being silly. 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 thing you could do. So it is good to have a reason why you hate some things and you like others.
