The Three Little Pigs

There were three little pigs once, and they lived in a settlement on the outskirts of the forest. The three pigs were siblings who shared a cute little house with their mom.
The kids' mom gave them a speech one day: "It's now up to you to find your own path in the world. You can fend for yourselves now, so go out and make shelters."
Intent on constructing the finest houses possible, the three pigs ventured out into the woods. The first pig used straw because he thought it would be cheap and simple to construct. The second pig decided to use sticks to construct his house because he believed they would be more durable. The third pig, however, being the most prudent and astute, used bricks to construct his dwelling.
The big terrible wolf came upon the three tiny pigs as they were building their houses. The wolf grinned evilly; he enjoyed nothing more than destroying the piglets' homes and feasting on them.
The first pig, seeing the wolf approaching, hurried into his straw hut, where he felt safe from harm. The little pig just escaped being eaten when the wolf blew down his straw house with one enormous puff.
When the second pig spotted the wolf approaching, he thought he would be safe in his stick house. The wolf, however, blasted the stick house down with one great huff, and the small pig raced out, narrowly avoiding being eaten.
When the third pig heard the wolf approaching, he thought he was safe inside his brick house. No matter how hard he tried, the wolf's huffing and puffing weren't enough to bring down the brick home. With his pride crushed and stomach growling, the wolf left.
The three little pigs built a house of brick and lived happily ever after. The lesson we should draw from this is that it's better to err on the side of caution and prepare for the worse.
