Christopher John Francis Boone says, "I know all the countries of the world and their capital cities and every prime number up to 7,057" [2]. Why does he introduce himself in this way?

This question is about "The Curious incident of the dog in the nighttime."

He presents himself that way because he is autistic.

Explanation:

Christopher is bullish and for that reason, we can conclude that his mind does not work like the mind of people who do not have this mental disorder. Like some bulls, Christopher has a very good memory and usually recalls very detailed things from elements to which he has a certain fascination. This fascination makes him present himself along with the things that are important to him, such as knowing the names of all countries and their capitals, as well as knowing all prime numbers up to 7.057.

the correct answer is c. usually the language, and its emotional insight, that is how feelings and attitudes are expressed through language, are not quite present in film adaptations. despite that, it is a factor that a fan may either not notice or not care much about, especially compared to the other factors.
