Once upon a time there was a black Labrador dog who always stayed beside his master, playing with him all the time and waving his tail from one side to the other, showing how happy it was; but after his master died in a car accident, the black Labrador dog stopped playing around and never again waved his tail from one side to the other.
One day, the black Labrador dog woke up being a black cat, and since then, he is always alone, wandering around the streets, growling to anyone who crosses his path and giving them bad luck.
The end.
