Moonlight pooled on the porch as Molly and Bill slipped through hedges, wearing matching masks. The children’s party glittered behind the curtains: streamers, clowns, and sugar on the air. Molly crouched at a window, handing Bill a tiny flashlight shaped like a toy. The plan was simple: grab every present, ignore the confetti, and sprint away before the singing starts. Inside, a timer chirped. Bill froze, listening to footsteps and a squeak of a party horn. Molly leaned closer, studying the gift table stacked with bright boxes and one bag marked For Games Only. She smirked. “Ready, Bill. Presents only.” Bill stared at the keypad. “Count us in. I’ll open it.” The lock clicked, meek as a housecat. Molly slid the window latch wider and ushered Bill forward, guiding him with sharp whispers and sharper elbows. “Remember: quiet hands, loud laughs.” The DJ called everyone to the next game, and everyone actually cheered like obedient pigeons. Bill lifted a bow-tied box in slow motion, as if it might bite. “Steal gently. Leave bows, okay.” A cheer rolled over them. They vanished with twenty squeaky prizes, leaving only suspicious wrapping paper and one lonely balloon that floated, offended, into the night.
