Molly crouched behind the frosting covered mailbox, listening to the neighbor’s garage door chirp like a robot. Beyond the curtains, the children’s party thumped with unicorn music and the unmistakable rustle of gift paper being wished into existence. Bill checked the bag he’d stolen from a costume store; it still smelled of fake mustaches and glitter. “Bill, stay silent, please tonight.” Molly offered the line like a hunting whistle. Bill mouthed an apology to the universe. “I am a whisper, mate.” The plan was simple: slip in during the “Any minute now!” stage, swap their names onto the thank you cards, and bag every present before the clapping started. Molly practiced the smile she used on security guards. It looked like sincerity had been mugged. Bill held up a clipboard labeled INVENTORY, which was really just a grocery list of bribes for the babysitter. “No stealing toys with eyes.” Molly nodded toward the giant stuffed robot by the doorway. “Only presents, no giggles, deal?” Bill grinned, then winced when the grin made his false teeth click. They waited for the cake server’s cue, counting down silently like professional burglars with manners. Somewhere, a child shrieked, and their courage recharged instantly.
