The fox's tail was stuck in a rock and had to be cut off.
Later when another fox saw him
“Why did you cut off your tail?” it asked.
The one with the tail cut off;
“I feel so happy.
I am soaring with my joy, ”said it.
Then the other fox cut off its tail.
But instead of happiness, it suffered severe pain.
Come to the fox immediately; "Why did you lie to me?" said.
Fox; “If you tell the other foxes that you are suffering, they will never cut off your tail and make fun of us.” said.
These two foxes told the other foxes about their happiness (!).
So most of the foxes cut off their tails.
When the majority passed on to them, this time they started to make fun of those with tails.
