The way sadness works is one of the strange riddles of the world. If you are stricken with a great sadness, you may feel as if u have been set aflame, not only because of the enormous pain, but because your sadness may spread over your life, like smoke from an enormous fire. You may find it difficult to see anything but ur own sadness, the way smoke can cover a landscape so that all anyone can see is black. You may find that happy things are tainted with sadness, the way smoke leaves its ashen colors and scent on everything it touches. And you may find that if someone pours water all over you, you are damp and distracted, but not cured of your sadness, the way a fire department can douse a fire, but never recover what has been burnt down.
