One day, a boy named Tim found a mysterious toy gun in his room. He did not know where it came from. He was very happy to play with it. He ran around the house and made "bang bang" sounds.
His sister, Sue, saw Tim with the toy gun and wanted to play with it too. Tim did not want to share the toy gun with his sister. They began to quarrel, and they both cried. Their mom heard the noise and came to see what was wrong.
Mom told Tim and Sue that they needed to share the toy gun and play together. She said it was more fun when they played together. Tim and Sue stopped their quarrel, and they both played with the toy gun. They had a lot of fun and were happy.
