Here's a short story:

There was once a young bear who lived in a small cave in the woods. His cave was comfy, warm, and dark, and had a bit of a yard in front of it. The bear lived with his mother and father, and spent his days walking around and his nights curled up asleep. He liked to look for berries to eat. His favorite berries were blueberries, but he would eat any berries he found: strawberries, raspberries, cherries, anything. 

There was a river near the bear's cave, and he loved to sit on the bank and look at the fish and frogs, and at his own reflection in the water. One sunny afternoon, when he was looking into the river, he saw a family of ducks swimming by. He got up and followed them. They swam along in the river, and he walked along the bank. They traveled like this until they reached a small clearing in the forest. The bear stopped and looked around, and saw that the clearing was completely filled with blueberries -- more than he had ever seen! 

The young bear ate his fill of blueberries, then took home as many as he could carry in his paws. He went to bed happy. It was a wonderful day. (End of story)
