Question

why did Mourad come to Aravs home in the morning and how did Arav react to that

Answer 1

One reason why riding the horse was such a surprise was the result of this cognitive dissonance between what reality presents and what one's mind knows to be true. Aram knows that his family is poor and yet the spectacle the beautiful white horse and the opportunity to ride it is a reality that would not "permit" him to believe what he saw.

Another reason why he is surprised is because he knows that Mourad stole the horse. He knew that Mourad stole the horse and Aram knows that "No member of the Garoghlanian family could be a thief." The tribal connection and faith that Aram has is one that prevents him from embracing the idea of theft. Seeing the horse in front of his window and his cousin riding on it leads him to recognize that Mourad broke convention in stealing the horse. As a result, Aram is surprised at the reality that is in front of him and the process it took to cause that reality to materialize. This chasm between reality and the events that precipitate it are another source of his surprise in the story.
