Once upon a time, there was a Hen and a Cow.
Every night, they would meet in the farmyard, raise their heads, and track the transient motions of the stars: bright balls, moving crazily through a big pot of purple sauerkraut. The Stars!
Cow saw the stars as big and close, Hen saw ‘em as small and far away.
Every evening was the same.
Then something happened... One night, the moon was fuller and brighter than usual, and its light didn't allow anything else to be seen. Only the big, incredibly strong silvery super ball, taking light from everything and everyone.
So, the Cow and Hen climbed the barn ladder to see it better. But no such luck! They could see nothing except the big and majestic ball.
It looked like a flake of butter!
And that is how Cow and Hen agreed. They finally saw the same thing: a balloon hung in the Universe! Size and distance no longer mattered...
And they all lived happily ever after.
