The thought of change is very difficult to think about. Whether it's changing schools, moving house or welcoming a new child into the family. It's definitely a difficult concept for anyone in their right mind to digest. However, Christopher Boone in The Curious Incident of the Dog in the Night-Time is far from having a decent mind. Someone with a similar mindset to his can't even conceive the idea of ​​changing his daily routine. Christopher has autism and this limits his ability to welcome new elements into his day. Christopher's behavior does not change over the course of the novel. Although he may seem to improve himself in terms of social stability, his personality has actually not changed at all. Whenever it seems that Christopher has changed, it is actually a misunderstanding, since Christopher only behaves this way out of mere childish instinct. Furthermore, Christopher's habits do not change. He still has apprehensions about physical contact, still gets along better with animals than humans, and is very particular about germs. Finally, his abilities to interact with those around him are no different. He still feels uncomfortable around strangers, still can't read human emotions, and still learns better visually than auditorily. Ultimately, Christopher Boone does not change over the course of the novel. It's not Christopher's fault, though, because he can't control it. Autism prevents a person from changing, as a person with ASD will accept being in a familiar environment with routine and structure. Christopher may also have ADHD, something common in children with autism. This would explain her obsession with small details, and with... middle of paper... she can't read human emotions at all, nor can she understand most jokes or metaphors. This shows that Christopher is a very straightforward person and insists that everything else conforms to this. Furthermore, Christopher, like many other children, prefers the visual learning style to the auditory one. This is shown consistently throughout the book whenever he uses a picture, diagram, or any other type of drawing to make his point. In conclusion, Christopher Boone faces many limitations during his journey. He may find a way to overcome some small dilemmas, but that doesn't mean that he, as a person, has changed. In the end, a person remains the same, although he or she may occasionally hide his or her weaknesses to confide in society's idea of ​​perfection. Everyone has their own flaws, even Christopher, and a person can never fix a flaw permanently.
