One day, a family went to the park. They were very calm and happy. The sun was bright and the sky was blue. The family played with a ball, and they laughed a lot. They also had a big picnic with lots of yummy food.
Then, a big dog entered the park. The dog was very friendly and wanted to play too. The family said, "Come play with us, dog!" The dog played with the family, and they had even more fun.
But then, something unexpected happened. The big dog took the ball in its mouth and ran away very fast. The family was sad and said, "Oh no, our ball is gone!" But the dog came back with a new ball, even bigger and more colorful. The family was so happy and said, "Thank you, dog!" They all played together and had a great day at the park.
