Once upon a time, there was a dog named Max. Max had a favorite toy, a red ball. He loved to play with it every day. One day, Max went to the park to play with his ball. As he was playing, he saw a little boy with a blue ball. The little boy wanted to play with Max, but Max didn't want to share his original red ball. The little boy said, "Can we play together? I have a ball too." Max replied, "No, my ball is the best. I don't want to tie with your ball." The little boy was sad and walked away. Max felt bad and realized he was being selfish. He went to find the little boy and said, "I'm sorry. Let's play together. You can lead the game and we can use both of our balls." The little boy was happy and they had so much fun playing together. Max learned that it's better to share and play with friends than to be selfish.
