“Cloud, be my messenger. Soak up the pool outside my window and carry it over fences and forests to the sorrowful house where my loved one waits. You will recognize it by the candle burning in the window. Do not delay! Those other puddles will muddy the message, keep you from getting there fast. Carry, cloud, my love exclusively, over the millions of lifeless clouds, under a guiding invisible hand.
