Moonlight skimmed the hedges while Molly and Bill squirmed behind a collapsing inflatable dinosaur. Molly adjusted her headlamp until it glowed like a polite firefly. Bill held a clipboard made of cardboard, because he believed confidence was a key. “Are you sure this is the right house?” Molly asked. “Relax, I scoped the driveway; the car seats match the mailbox decals,” Bill replied. They crept toward the doorway, stepping over a trail of glitter that sparkled like evidence. “What’s the plan if the kids notice?” Molly whispered. “We blame the magician,” Bill said, and flipped open a rubber rabbit that squeaked “surprise.” Molly snorted. “Too loud. Borrow your inside voice.” Bill pointed at the present pile. “I’ll grab the big ones—coincidentally the ones with the loudest tape. You take the smaller loot.” Molly nodded, then lifted her cupcake-napkin map. “Then we exit through the snack table,” she said. Bill paused, listening to distant laughter. “Do you think they’ll offer us juice boxes?” Molly blinked. “Only if we confess to being very tiny thieves.” Doorbell chirped nearby, mercifully. “If we get caught, we’ll say we’re just evaluating gift wrap for safety,” Molly said. “Perfect—then I’ll negotiate with the clown’s rabbit and request batteries,” Bill replied.
