The Curious Incident of the Dog in the Night-Time- Post 1

After reading chapter 61, I found it odd when Christopher boldy claims that heaven doesn't exist, and this observation lead to my realization that Christopher cannot understand abstract concepts. Unless something is completely literal, Christopher is confused by it. The ideas of faith, sarcasm, and metaphors are to Christopher as a foreign language is to one of us. Such literal interpretations of speech would make having a casual conversation with Christopher very difficult, and explains his lack of an expansive social life.
