One day a man was driving a horse and a donkey to the market. There was a heavy load on the back of the donkey. There was no load on the back of the horse. On the way, the donkey said to the horse, "Please share my load. It is very heavy for me." The horse said, "Heavy or not. I don't care. It is your load and you must carry it yourself. Don't ask me to share it." The donkey said nothing.They walked on silently. After a while the donkey sank down on the road. His mouth was foaming. So the man removed the load from the back of the donkey. He placed the whole load on the back of the horse. As they walked on, the horse thought, "I did not share the heavy burden of the donkey. Now I will have to carry the whole burden all the way to the market."
