"(a) Are the skies you sleep under likely to open up for weeks on end? (b) Is the ground you walk on likely to tremble and split? (c) Is there a chance (and please check the box, no matter how small that chance seems) that the ominous mountain casting a midday shadow over your home might one day erupt with no rhyme or reason? Because if the answer is yes to one or all of these questions, then the life you lead is a midnight thing, always a hair's breadth from the witching hour; it is volatile, it is threadbare; it is carefree in the true sense of that term; it is light, losable like a key or a hair clip. And it is lethargy: why not sit all morning, all day, all year, under the same cypress tree drawing the figure eight in the dust? More than that, it is disaster, it is why not overthrow a government on a whim, why not blind the man you hate, why not go mad, go gibbering through the town like a loon, waving your hands, tearing your hair? There's nothing to stop you---or rather could stop you, any hour, any minute.
