Once upon a time, there was a boy named Tim. Tim loved to play outside. He liked to run and jump in the grass. The grass was soft and green. Tim thought the grass was harmless, so he played there every day.
One day, Tim found a shiny rock in the grass. The rock was dirty, so Tim wanted to polish it. He used a cloth to rub the rock. The rock became shiny and clean. Tim was happy with his shiny rock.
Tim showed his shiny rock to his friends. They all liked it. They wanted to find their own shiny rocks. So, they all went to the grass to look for rocks. They found many rocks and polished them too. They had a fun day playing with their shiny rocks in the harmless grass.
