why do you think the boys returned the horse
The two boys belonged to the family of Garoghalanian which was a part of the Armenian tribe. Although they were poor but the tribe was known for their honesty and trust. They never took advantage of anyone for fulfilling their own interest. While the two boys were spending their time with the stolen horse and enjoying their rides, their morals gave them a call. They understood that they were denigrating their tribe. They were also afraid because if the tribe people knew about the stolen horse they would get admonishment for doing a something that was in opposition to the customs of their tribe. So they returned the horse.
