RE: Why do you think Mark Haddon includes the drawings and diagrams Christopher creates?
I think the author includes the diagrams to show what is going on inside Christopher's head. Also, I think since Christopher is so intelligent, he knows a lot of things that the readers might not so the diagrams are to explain things as well.
I agree because although he had problems he was still smart
