Cat and Dog were Friends

Once upon a time in a fairy tale land a cat and a dog were friends. One night, the cat invited the dog for a party at his house. 

The cat played the fiddle（演奏小提琴）. The dog happily clapped his hands. Suddenly, they saw a cow flying in the sky. It jumped over the moon. The dog laughed. Just then, they saw a dish and a spoon from the party running away together. And they laughed even louder. After that they became the best friends. 

Moral of the story : 

Enemies could also become good friends. 
敌人也可以变成好朋友。
