Plot
There once was a horse and a stag who argued over who got to eat in the best meadow. They were constantly fighting over who got to eat there. The horse went to a hunter and made an agreement to hunt the stag. The horse had agreed to be saddled so that the hunter could ride it. The stag ran away in fear when he saw the hunter. After the stag was gone the horse asked for the saddle to be removed. The hunter refused, and took the horse as his own.
