Moonlight draped the backyard, spilling silver over the plastic balloons and a rogue clown poster. Molly crouched behind a folding table, eyes scanning the chaos of glitter and crayon drawings. Bill slipped a flashlight under his jacket, its beam flickering like a nervous firefly. The children’s party smelled of sugar and spilled juice, a perfect cover for their caper. He whispered, “We’ll slip through the dessert table first,” and the words floated on the night air. Molly answered, “Then we hit the gift pile, quick as cat.” They moved in sync, their shoes squeaking on the vinyl floor, careful not to alarm the giggling guests. A stray balloon drifted by, bobbing like a nervous sentinel, while a stray cupcake left a sticky trail on the floor. Bill nudged a piñata, its papier‑mâché body rattling, a signal that the moment was right. “Now,” Molly hissed, “grab the boxes!” Their gloved hands dove into the mountain of wrapping paper, ripping ribbons as fast as a windstorm. Laughter erupted from the children, oblivious to the heist unfolding beneath a canopy of streamers. The duo vanished into the night, pockets full of toys, leaving only empty boxes and bewildered parents and sighing at sunrise.
