Moonlight slanted through the window of the community center, turning streamers into pale jellyfish. Molly checked her tote, which smelled faintly of peppermint and borrowed courage. Bill quietly practiced quiet-footed steps in sneakers that squeaked with reluctant pride. Mischief had a rhythm, and tonight’s rhythm wore a party hat. The plan wasn’t complicated, just audacious enough to be funny. They planned to break into the children's party in the gym, with presents stacked like treasure reef, and steal all the presents. They rehearsed movements in the hallway: one distraction, two scoops of squinting, three exits labeled by optimism. Molly wanted to steal the sparkle, Bill the opportunity to retire his alarm clock. The door clicked open, and a radio whispered from a staff desk. A clock ticked, cavorting between seconds. Molly leaned closer, eyes gleaming with mischief that felt almost tender. Bill shrugged into his bravest grin, which was mostly admiration for the plan’s audacity. "Careful, no crying, sweetheart," muttered Molly, as if reciting a lullaby to burglars. "We leave the napkins and the confetti." "We glide, we grin, we depart." "Stay nimble, friends." They moved toward the stage door, hearts thudding like bass drums, grinning at the absurdity tonight.
