In Richard Haddon's novel, The Curious Incident of the Dog in the Night-Time, the main character and narrator, Christopher Boone, suffered from aspergers syndrome which is a form of Autism. This caused many of his actions to seem impractical and we do not understand why he acts this way, but it also caused him to act in the most basic and simple of human ways. Christopher's parents on the other hand did not suffer from autism, or any other kind of disability yet we still do not understand their actions.
Many of Christopher's actions we observe throughout the novel are difficult to explain and understand.
