Once upon a time, there was a little boy named Tim. Tim liked to play with his toy chain. One day, Tim was playing outside with his toy chain. He was swinging it around and around. He was having so much fun!
But Tim was being careless. He did not see the big rock near him. As he played, he tripped on the rock and started to fall. Tim's friend, Sam, saw what was happening. Sam yelled, "Tim, watch out!"
Tim looked up just in time to catch himself before he fell. He said, "Thank you, Sam! I was being careless with my toy chain. I need to be more careful when I play." Sam smiled and said, "Yes, always be careful, Tim!" From that day on, Tim always played carefully with his toy chain.
