Those are both beautiful stories.
Don't see how anyone can say they don't have feelings or morality.
The man who owned her was an accomplished rider who enjoyed the challenge of such a horse. Now, this man had a girl friend who suffered from muscular dystrophy. She could not walk and her range of movement was very limited. He would bring his GF to the stable, set her on his beautiful, dangerous horse, (bareback, the GF could not sit in the saddle comfortably) the horse would walk around as delicately and carefully as if she were walking on ice. He would mount one of his other horses and they would spend an hour or two on the horses just walking leisurely around the farm.
That horse made a conscious choice to be gentle with that woman. That is morality. To call it anything else is disingenuous.
Beautiful story, thank you for sharing this.
