Rain ticked against van while Molly studied the glittering house. “Bill, that fortress contains balloons and presents enough to retire.” Bill adjusted his ridiculous tuxedo, borrowed from a doll yesterday. “Molly, we need disguises, timing, and an explanation for everything.” Molly unveiled two hats, a whistle, and an official-looking clipboard. “I already forged invitations, though the glitter smudged our aliases.” Outside, parents carried casseroles past them, unaware of criminal ambition. “My alias is Captain Snuggle; yours is Duchess of Parking.” They approached the gate, where cardboard dragon guarded the driveway. “Smile naturally, Bill; criminals who smile naturally look especially guilty.” A toddler opened the door, wearing crown and wielding frosting. “Greetings, monarch. We represent the International Society of Birthday Logistics.” The child stared, then smeared frosting across Bill’s rehearsed mustache. “Excellent inspection, Majesty. We require access to the treasure chamber.” The toddler giggled, leading them past streamers and unattended gifts. “Phase one succeeds! Pretend confidence, avoid children, locate largest boxes.” Molly lifted a package, but it jingled like loose marbles. “That is treasure or a furious tambourine; both deserve caution.” Then the lights flashed, revealing parents wearing identical burglar masks. “We are surrounded, Molly. Improvise something charming before I surrender.”
