Once upon a time, there was a little dog named Spot. Spot loved to run and play with his friends. One day, Spot's friends asked him to join them for some exercise. They wanted to race to see who was the fastest. Spot started to worry because he had never raced before.
The race began, and Spot ran as fast as he could. He was running so fast that he tripped and fell. Spot felt silly for falling, but his friends helped him up. They told him not to worry and that everyone falls sometimes.
Spot decided to try again. This time, he ran even faster and didn't fall. He finished the race and was so happy. Spot learned that it's okay to feel worried and silly sometimes, but it's important to keep trying. And that day, Spot and his friends had lots of fun playing and exercising together.
