Once a horse was tied and was trying to get loose, and a demon came and let it go.

The horse got into a farmer's farm and began to eat the crops.

The owner of the farm got angry, took his rifle and killed the horse.

Then the owner of the horse also got angry, he took his rifle out of revenge and killed the owner of the farm.

Then the farm owner's wife saw him and killed the horse's owner.

Then the son of the owner of the horse became very angry and killed the wife of the owner of the farm...

The angry neighbors killed the boy and burned his house; then they asked the demon;

Why did you do all that?

The demon responded, I just let the horse go.
