Feeling Nostalgic - One of My Memorable Kid Stories

Once upon a time, there lived an old sick lion. He was so weak that he could not go out in search of food. One day, he summoned all the animals in the animal kingdom telling them that he was sick so they should visit him one after the other with food. Every animal that went in never came out.
Now, it was the turn of the cunning fox to visit the lion. On visiting him, the fox went and stood at a distance from the lion's cave. After an invitation from the lion to come him, the fox politely refused making known to the lion that he realized every animal that visited him never returned.

Moral of the story: "The Wise man learns from the misfortunes of others "
