I think about pinball, and how being a kid's like being shot up the firing lane and there's no veering left or right; or you're just sort of propelled. But once you clear the top, like when you're sixteen, seventeen, or eighteen, suddenly there's a thousand different paths you can take, some amazing, others not. Tiny little differences in angles and speed'll totally alter what happens to you later, so a fraction of an inch to the right, and the ball'll just hit a pinger and a dinger and fly down between your flippers, no messing, a waste of 10 p. But a fraction to the left and it's action in the play zone, bumpers and kickers, ramps and slingshots and fame on the high-score table.
