One day, a little boy named Tim found a big, interesting rock. It was purple and shiny. He picked it up and stared at it. He thought it was the most beautiful rock he had ever seen.
Tim showed the rock to his friend, Sally. "Look at my purple rock," he said. Sally stared at the rock too. She thought it was very interesting. "Can I hold it?" she asked. Tim said yes, and they both played with the rock.
As they played, the sky got dark and it started to rain. The rain made the rock slippery. Tim tried to hold on to it, but it fell out of his hands. The purple rock rolled away and fell into a big puddle. Tim and Sally were sad. They couldn't find the interesting rock anymore. The rain had washed it away.
