One day, a happy boy named Tim went to the park with his mom. Tim had a rubber ball that he loved to play with. The ball was red and blue and very bouncy. Tim was so excited to show his ball to his friend, Sam.
At the park, Tim found Sam and said, "Look, Sam! I have a new ball!" Sam looked at the ball and smiled. "Wow, Tim! That's a great ball!" They started to play with the ball, throwing it back and forth.
As they were playing, a big dog came running up to them. The dog saw the ball in the air and jumped to catch it. The dog caught the ball in its mouth, but as it landed, the ball popped! Tim and Sam were sad that the ball was gone, but then the dog's owner came over with a new rubber ball. "I'm sorry my dog popped your ball. Here, you can have this one." Tim and Sam were happy again, and they all played together with the new ball.
