Once upon a time, there was a big, thick comet flying in the sky. It was very fast and bright. The comet wanted to finish its long journey across the sky and find a friend.
One day, the comet met a little bird. The bird was scared of the comet at first, but then they became friends. They played together in the sky, and the bird flew with the comet. They were very happy.
But one day, the comet had to finish its journey. The bird was sad, but the comet told the bird that they would always be friends. The bird learned that even if friends go away, they are still in our hearts. And that was the surprise - the comet never really left, because it stayed in the bird's heart forever.
