Read the following text carefully.
 

    It was the coldest winter ever. Many animals died because of the cold.

    The 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 one from the other. They began to die, alone and frozen. Then, they had to make a choice; either accepted the quills of their companions, or disappear from the Earth.

    Wisely, they decided to go back to being together. They learned to live with little wounds caused by the close relationship with their companions in order to receive the heat that came from the others. This way they were able to survive.
