One day a hare saw a tortoise walking slowly along and began to laugh and mock him. The hare challenged the tortoise to a race and the tortoise accepted. They agreed on a route and started off the race. The hare shot ahead and ran briskly for some time. Then seeing that he was far ahead of the tortoise, he thought he’d sit under a tree for some time and relax before continuing the race.
He sat under the tree and soon fell asleep. The tortoise, plodding on, overtook him and finished the race. The hare woke up and realized that he had lost the race.
