Moonlight pooled on the daycare fence as Molly checked the banner for loose tape. Inside, a squeaky speaker played “Party Time,” and the hallway smelled of frosting and balloons. Bill crouched by the hedge, thumb on a cheap lockpick, ears tuned for parental footsteps. Their genius plan was to be polite thieves: wait for the gift-opening circle, then harvest every present before anyone noticed the wrapping paper getting thinner. Molly said, “Quiet, Bill.” Bill answered, “Got it.” Molly asked, “Keys?” Bill replied, “Try this.” Molly breathed, “Success!” Bill said, “Grab presents.” Molly warned, “No alarms.” Bill laughed, “Run!” Molly added, “Then wrap the mess.” Bill finished, “Kid asleep, saints.” They slipped through the gate, crossed the carpeted maze of gift bags, and filled their canvas sacks with brightly boxed loot. Somewhere, a clown practiced a high note, but it sounded like background music for crime. Molly counted, Bill grinned, and together they moved with the careful, absurd confidence of people who definitely shouldn’t know how to open childproof locks. They paused by the stage, listening to cheers swell, then slid a tower of presents into the shadows. Bill joked softly with his eyebrows as Molly bagged the last ribboned box.
