It was the coldest winter ever. Many animals died because of the cold.
A group of hedgehogs, realizing the situation, decided to group together to keep warm. This way they covered and protected themselves; but the quills of each one wounded their closest companions.
After a while, they decided to distance themselves from each other. Slowly, alone and frozen, they began to die. So, they had to make a choice: either accept the quills of their companions or disappear from the Earth.
Wisely, they decided to go back to being together. They learned to live with the little wounds caused by the close relationship with their companions in order to receive the heat that came from the others. In this way, they were able to survive.
Moral: The best relationships are when each individual learns to live with the imperfections of others and focuses on the other person's good qualities.
