Rain polished the cobblestones outside the community hall, turning every streetlamp into a trembling gold coin. Molly crouched behind a hedge, wearing a borrowed magician’s cape and the expression of someone who had never successfully pulled anything from a hat. Bill lay beside her in a tuxedo two sizes too small, his fake mustache drooping like a wet caterpillar. He clutched a sack labeled EMERGENCY BALLOONS, which contained only rope, biscuits, and an alarming number of rubber ducks. Molly whispered, “Presents wait beneath clown mural; enter disguised as entertainers.” Bill replied, “I hate children’s parties, but I hate affordable security even more.” The hall throbbed with music, shrieks, and the unmistakable percussion of a parent losing an argument with a balloon. Through the windows, they saw children circling a table piled with brightly wrapped boxes. A cardboard dragon guarded the entrance, its painted eyes accusing every adult who approached. Molly produced two juggling balls from her pocket. Bill produced one and immediately dropped it down his trousers. The ball rolled beneath the hedge, where a terrier seized it and fled. Bill followed, crawling with the dignity of a diplomat escaping an opera. Molly watched dog vanish, then adjusted cape. A volunteer mistook them for entertainers and opened the door. They swept inside, stuffing every present into the sack while Bill distracted everyone with juggling.
