Life Is Like A Bad Metaphor
Be careful. Because life is unpredictable in ways that you can't imagine. We keep to ourselves, make our own plans, and feel secure in our routines, and we never really think about how close to the edge of chaos and destruction we are. And if we do begin to think of such meaningful and enlightening things, we become distracted by our rumbling tummies.
If you sit down at a fancy restaurant and order your favorite meal, an eggplant parmisiano with a light salad and garlic bread, you would expect to recieve what you ordered. If you were to, say, be served the severed head of your sworn enemy, you would be quite surprised but delighted by your luck, just as warlords and kings of the past would have been. Being served an inedible human head certainly doesn't happen often, but it definitely does happen. Life's surprises can be very pleasant.
