"...Nothing in the universe can be the same if somewhere, we do not know where, a sheep that we never saw has-- yes or no?-- eaten a rose...

Look up at the sky. Ask yourselves: is it yes or no? Has the sheep eaten the flower? And you will see how everything changes...

And no grown-up will ever understand that this is a matter of so much importance!"

Antoine de Saint-Exupery "The Little Prince"
