A long, long time ago a little girl was walking through a park. In the middle of the park there was a tree with a sign on it. The sign said "I am a magic tree. Say the magic words and you will see."

The girl tried to guess the magic words. He tried abracadabra, supercalifragilisticexpialidocious, tan-ta-ra, and many more... but none of them worked.

Exhausted, she threw himself on the floor, saying: "Please, dear tree!" and suddenly, a big door opened in the trunk. Inside everything was dark, except for a sign which said "Carry on with your magic." Then the girl said "Thank you, dear tree!" With this, she could see the inside of the tree and saw to a great big pile of toys and candies.

The little girl brought all her friends to the magic tree, and they had the best party ever. This is why people always say that "please" and "thank you" are the magic words.
