Once upon a time, not very long ago, a girl named Megan was camping out in her back yard one night. She had a good tent and a warm sleeping bag and her mother and dad brought out some hot chocolate before they went in to bed. After they left, Megan watched the night for a while. She was feeling pleased with the moon and the sky and the stars and the trees because everything was perfectly right and just the way that it was. She liked the moon the most of all; it was round and full and especially bright.
"We'll be together all night long," she told the moon. "I'll look up and you'll look down and all the night through I'll be watching you and you'll be watching me. And when I finally fall asleep we'll dream together, drifting high in the starry sky until the dawn arrives."
Time went by in an idle way, sliding slowly through the night between the stars in the sky. Megan's eyes began to get tired. Soon they were heavy and wanted to close. But just as she started to fall asleep, all of a sudden without any warning, the moon began to disappear.
Slowly at first, then faster and faster, more and more it got less and less. The bright full circle was soon sliced in half, then half of a half and a quarter of a quarter until all that was left was one last pale sliver of silver light. A moment passed, another passed too and then all in an instant the last little piece of the moon was gone.
