"He said...he said that my smile stretches across my face like a butterfly...Then he said something about my laugh. He said my laugh was a rose, crashing water. He said my laugh was a sudden silvery wave."
"There was once a poet named Dante who fell in love with a woman named Beatriz. It seems that Beatrizes provoke incommensurable loves."
(---from The Postman by Antonio Skármeta)
