One day, a boy named Tim found a big helmet in his room. It was clear and shiny. He put it on his head and went outside to play.
In the yard, Tim saw his friend, Sam. Sam wanted the helmet, too. They both yelled, "It's mine!" They were not happy and did not want to share.
Tim's mom came outside and saw them fighting. She said, "You both can use the helmet. Take turns, and then you can play together." Tim and Sam listened to her. They took turns wearing the helmet and played all day. They were happy again.
