Molly watched the backyard lights flicker through the fence while kids screamed for prizes they hadn’t earned. A clown car of cupcakes sat by the door, and a bored magician stared at a balloon like it might bite. Bill adjusted his clown-nose mask, trying to look stealthy instead of ridiculous. “Bill, listen—the kids are chanting. We slip in during the balloon song.” “Copy. I brought clown nose decoys; no one suspects a face that funny.” Molly smirked. “Your plan is great and slightly illegal.” Bill pointed at the gift table. “That’s the theme. Which presents first—games or the noisy ones?” “Noisy. Parents love chaos, until it’s gone.” Bill nodded, already itching for Lego. “Agreed. I’ll grab the Lego castle.” “I’ll take the dollhouse; it’s basically a tiny landlord.” The music swelled; they paused like naughty statues. “If a parent asks, we’re workshop assistants.” Molly swallowed a laugh. “And if a child asks why we’re carrying tape, huh?” Bill adjusted the roll. “We say it’s for wrapping their future awesomeness. Remember, we leave one box: socks for plausible innocence. Obviously boss.” They waited for the countdown, then slid between legs and wrapping paper, silent except for Molly’s stomach doing a hiccup now.
