Once upon a time, there was a high tree in a park. Under the tree, there was grass. Two birds lived in the tree. One bird was red and the other bird was blue.
One day, the red bird and the blue bird had a quarrel. The red bird said, "This grass is mine!" The blue bird said, "No, this grass is mine!" They were not happy.
A little girl came to the park. She saw the birds and said, "Why do you quarrel? You can both play on the grass." The birds stopped quarreling. They played on the grass together and became friends.
