Orbiting

I looked up at the moon and said, "Do you ever get tired of living in the Earth's orbit?"

The moon said, "Once. It was about a hundred thousand years ago. I'd had enough and left. I wandered aimlessly. Then for a while I was a moon around Jupiter. We got along really well at first. But I was always complaining about the Earth and Jupiter got tired of hearing it and kicked me out of its orbit."

I said, "Why did you come back?"

The moon said, "I got a letter from the Earth saying it decided to create life forms, and it needed me to manipulate the appropriate weather systems necessary to sustain living organisms."

I said, "I guess in the end we all need to feel wanted."
