There are two stoves in the kitchen.
Every evening, two dancing flames would appear on the stove.
One of them is fat and the other is thin.
The thin flames always show off to the fat flames: "Look at me, how slim I am! Only a slim flame can perform a beautiful dance!"
But later, why did it change its mind?
