The horse in "The Summer of the Beautiful White Horse" behaved in a calm and docile manner when the narrator, Aram, sat on him. This is evident from the following points:

First encounter with the horse:

- When Aram first saw the horse grazing in a field, he was struck by its beauty and approached it cautiously.
- The horse did not show any signs of aggression or fear, but simply continued to graze while keeping an eye on Aram.

Riding the horse:

- After befriending the horse's owner, John Byro, Aram was allowed to ride the horse.
- The horse stood still as Aram climbed onto its back, and then began to walk slowly at his command.
- Despite being a wild horse, the animal was gentle and obedient, responding to Aram's movements and voice cues without hesitation.

Reactions of others:

- Even the adults in the village were impressed by the horse's behavior, as it was rare to see a wild horse that was so easily tamed.
- When John Byro saw Aram riding the horse, he was pleased that the animal had taken to him so quickly, and allowed him to continue riding it.

Overall, the horse's behavior was one of trust and cooperation, responding well to Aram's gentle touch and commands. Its calm demeanor and willingness to be ridden made it a prized possession in the village, and brought joy to those who were lucky enough to interact with it.

When it was the narrator's turn to ride alone the horse didn't moved.So ,the narrator kicked into his muscles then it began to run but instead of running towards the field it began leaping over the vines and because of that the narrator fell from the horse.It happened every time whenever the narrator tried to ride it .
