Once upon a time, there was a boy named Tim. He loved to draw with his ink pen. One day, he saw a dull rock and thought it would be fun to draw on it.
Tim went to his friend, Sam. He said, "Look at my dull rock! I want to make it pretty with my ink pen." Sam smiled and said, "That's a great idea, Tim! Let's do it together."
They started to draw on the rock. They made it very pretty with many colors. Soon, the dull rock became a beautiful piece of art. All the kids in the town came to see it. They all loved it.
Tim and Sam were very happy. They learned that when they work together, they can make something dull become very beautiful. And that was the moral of their story: working together can make great things happen.
