Write a story with a moral lesson at the end?

You all know the Lion is the king of the forest. One lion king used to go everywhere in its kingdom with his advisors, the wolf and the fox. As lunch time approached, the king asked the wolf what we should do. The wolf said that the prey animals will be coming from the north. You wait hidden in the bush in the south. I shall wait in the west and the fox can wait in the east and ensure the prey do not escape to the east or west.
 
Good idea. so they all followed the plan. Along came a rabbit, ran helter skelter frightened  on seeing the fox and the wolf and straight into the lion, who with one swipe of its paw killed the rabbit. Next a donkey came by and met a similar fate. So did a deer. The lion felt they had sufficient food for their meal and asked the wolf of how we were going to share the meal. The wolf said that the fox can have the rabbit., the lion can have the donkey and he would partake of the deer. The lion knew the tastiest meat is that of the deer, and sensing the deviousness of the advisor wolf smacked him dead. Next he asked the fox for advice on sharing. The fox meekly replied that whatever way the lion wants to have the meal is fine and good. On hearing this the lion said you are a wise and good advisor, who is your guru? The fox humbly replied that the wolf was his guru.  Seeing the fate of the wolf the fox learnt from the wolf's mistake.
 
The moral of the story: You can and must learn from your mistakes. To err is human. But to repeat a mistake is foolish. However we need not keep making mistakes to learn life lessons. It is really wise to learn from other's mistake.
