Affection; If You're A Friend.

That day, is the most extreme snow season in Canada.
Many animals died from extreme cold.
In an area, there is a group of Hedgehogs (a kind of hedgehog).

They decided to stay in groups in a cave, to keep warm. They get closer to each other.
But when they got close together, their thorns wounded their closest friends.
After a while, they decided to keep their distance from each other.
As a result, they begin to feel the cold that froze, and eventually threatened to die.
So they must decide: accept the thorns of their friends, or die!
Wisely, they decided to re-unite.
They learn to live with small wounds from close proximity to their friends in order to feel the warmth.
This is how they survived and survived.
