A perfect fish

Once upon a time, there were two polar bears. They were good friends. They lived together, alone. They searched for food together and shared it. But food was becoming more and more difficult to find. One day, out the blue, they found a fish. But not just any fish. A perfect fish. The first bear couldn’t wait to eat it. The second bear thought about it and suggested that it would have been wiser for them to find another great fish to mate it with so that they would have more then enough food for the future. They would have to be patient but the idea was very good. The first bear agreed.
After much searching, they found it. Another perfect fish. While waiting for them to make many baby fish, they kept feeding off smaller fish they found, knowing that soon they wouldn’t have to worry about food any longer.
One day, the second bear had to leave his friend for a while. He had to go see his sick mother. He had to take care of her. He was sad to leave his friend but had no choice. He was away for a few weeks.
When his mother had recovered, he was very happy to be able to go back to his friend. He was impatient to see him and to enjoy with him a perfect meal. The result of their patience and their efforts. But when he arrived, only one fish was left. The first bear had eaten everything that they had worked for together. And he gave no explanation. He simply said “I’m sorry”, shrugged, and went to sleep.
The next morning, when the first bear woke up, his good friend was gone. The last fish had been eaten. Its carcass was lying next to him.
