Molly whispered outside the community hall beneath a moonless sky. “The balloons provide excellent camouflage; nobody suspects cheerful adult grownups.” Bill crouched beside her, disguised as a sweating birthday clown. “Then why are you wearing black, Molly, including black lipstick?” Molly peered through windows; children shrieked while parents guarded presents. “Because sophistication frightens security guards more effectively than ordinary criminals.” Bill steadied balloons tugging Molly toward a nearby roof gutter. “Your plan involves entering a children’s party, not robbing museums.” Molly rescued him, losing one eyebrow beneath an inflatable unicorn. “Exactly; museums rarely contain remote-controlled dinosaurs and chocolate fountains today.” Bill watched a magician announce cake-cutting with theatrical thunder inside. “Remember, we steal all presents, never cake; crumbs look suspicious.” Molly and Bill exchanged determined glances, approaching unlocked side door. “If anyone asks, we’re magical uncles delivering unusually expensive surprises.” Molly slipped through first; Bill dragged their balloon disguise behind. “Neither of us has nephews; your wand’s merely a screwdriver.” Bill’s sack snagged a doorknob, producing a festive crash nearby. “Details, Bill. Hold presents and smile like innocence owes money.” Molly waved as every child turned, firing unicorn’s squeaker accidentally. “Afterward, we divide fairly: you take toys, I take batteries.”
