Once upon a time there was a zero. The zero was open. Suddenly it started to shrink. It kept on shrinking and shrinking until it was so small, it was almost gone. It was now so very tiny, it could fit on the tip of a finger. 
The zero was so happy, it started to jump up and down. It kept jumping up and down until it was almost as tall as a tree. But then it jumped back down very quickly, and it started to shrink again.
The zero kept shrinking and shrinking until it was so small it could almost fit inside of a drop of water. It was so tiny that no one could see it.
But then, suddenly it started to grow bigger and bigger. It kept growing until it was back to its original size. 
The zero was so happy, it jumped up and down and shouted, “I’m back to my open size!”
