Molly and Bill crouched behind a hedge outside the community hall, dressed as an unusually nervous pair of birthday magicians. A paper crown dangled from Molly’s pocket, while Bill carried a velvet sack, three rubber chickens, and a forged invitation printed on a napkin. Through the windows, children shrieked around a mountain of brightly wrapped gifts. One enormous box trembled ominously, probably containing a puppy, or a determined uncle. Molly whispered, “The presents are stacked by the clown. We slip in, smile, and leave unnoticed.” Bill asked, “What if a child recognizes us?” They had studied the party schedule with criminal devotion: cake at noon, puppet show at twelve-ten, parental confusion at twelve-fifteen. Their escape route involved the kitchen, a laundry cart, and a conveniently unlocked side gate. Bill had practiced looking wholesome, though his smile suggested he had swallowed a fork. A gust yanked the napkin invitation into a puddle. Bill lunged, collided with a plastic flamingo, and sent it clattering beneath the hedge. Inside, an adult shouted for the magician. Molly straightened her paper crown and opened the gate with theatrical confidence. Bill followed, dragging the sack, while the flamingo squeaked under his shoe like an alarm designed by an optimist.
