Earth and Mars was partners in figure skating. The Earth has always been fond of it, but Mars.. Mars began to study with the Earth when he fell in love with it. They trained in winter on the lake, where the ice was too thick to fall. Every day Mars taught more and more tricks. They studied in the evenings and at night, while all the other planets were asleep in the house. Mars and Earth have already met. And all the planets often went to the performances of the Earth in figure skating. And so, another night on the frozen lake.
