Once upon a time, there was a big sky. In the sky, there was a comet. The comet was very original. It was shiny and bright. It moved fast in the sky.
One day, the comet met a star. The star said, "Hello, comet! Can I join you?" The comet said, "Yes, I permit you to come with me." So, the star and the comet went together in the sky.
They played and had fun. They made the sky look beautiful. All the people on the ground looked up and smiled. The comet and the star were very happy. They were best friends in the sky.
