Once upon a time, in a small house, there lived a little boy named Tim. Tim loved to play with his marbles. He had big ones, small ones, and some that were very pretty. He played with them all day long.
One day, Tim found a yummy candy. He was very happy and wanted to eat it. But, he was also playing with his marbles at the same time. By mistake, he put a marble in his mouth instead of the candy. He started to chew the marble. It was very hard and not yummy at all. Tim was scared and did not know what to do.
His mom heard him cry and came running. She saw the marble and quickly took it out of his mouth. Tim was safe now, and he learned a big lesson. From that day on, Tim never played with his marbles while eating. He knew it was not safe to do both at the same time. And the yummy candy? His mom let him eat it after all, but only when he put his marbles away.
