What are some paradox examples in the curious incident of the dog in the night time?

Haddon’s novel is full of paradoxes that transform it into a work of near genius. Christopher tells us that he does not understand jokes yet it is his very straightness that is the cause of the novel’s humour. Whilst interrogating Mrs Alexander he notes, ‘(she) was doing what is called chatting, where people say things to each other which aren’t questions and answers and aren’t connected … I tried to do chatting by saying, “My age is fifteen years and three months and three days.”’ Christopher cannot tell a lie and yet he confuses everything. He would seem to be a most unlikely narrator and yet he emerges as one of the most vivid of recent years. He never gives too much information away, and in the simplicity of his narration each reader is invited to find a means of interpretation and understanding.
