According to one interpretation of quantum mechanics, in the course of any event in which multiple outcomes are possible, every outcome occurs—one in this world, others in an array of parallel worlds. So in one world, I might write that I despise Katie Pearl and Lisa D'Amour's Terrible Things and Sibyl Kempson and Mike Iveson Jr.'s Crime or Emergency, both at P.S.122. In another, I might champion one show at the other's expense. In a third, I might never pen a word, as a racetrack win enables me to abandon my career and light out for regions rum-soaked and tropical. But in this world, I will celebrate both shows as appealing and eclectic (and perhaps heave a quick sigh for daiquiris unsipped).
