There was once a deer who was being chased by hunters. The deer knew that the hunters were trying to kill her, so she ran as quickly as she could in order to escape them.
The deer ran and ran, but she realized that she could not keep on running forever. Then she saw a hill in the distance, and she remembered that there was a cave in the side of the hill. "I can hide in the cave," thought the deer, "and the hunters will never find me there."
Confident in her plan, the deer quickly made her way to the cave and ran inside. The poor deer! Inside the cave was a lion who attacked the deer, killed her easily, and devoured her for dinner.
The moral of the story is that even the best possible plan can sometimes turn out very badly.
