Life is like an amusement park.
Some rides vigorously spin you round and round, until you lose all sense of certainty, except that you will throw up. Some are scenic and quiet, others grotesque and shrill. Some move at such velocity, your body contorts in dread, fearing you will fly off the track. Still others are slow, steady, and agonizingly predictable. A few are a thrill while they last; others are not worth repeating.
You go expecting to have fun, but you are wise to wear comfortable shoes.
