the Little Prince. Not important?
"And if I know - I, myself - one flower which is unique in the world, which grows nowhere but on my planet, but which one little sheep can destroy in a single bite some morning, without even noticing what he is doing - Oh! You think that is not important! ... If some one loves a flower, of which just one single blossom grows in all the millions and milliosn of stars, it is enough to make him happy just to look at the stars. He can say to himself: "Somewhere , my flower is there..." But if the sheep eats the flower, in one moment all his stars will be darkened... And you think that is not important!"
