Molly unrolled the hand-drawn map across the hood of the rusty van, stabbing her finger at a pink rectangle labeled "BOUNCY CASTLE." "We go in through the back garden while the clown has their attention," she whispered. "Why are we whispering?" Bill asked. "We're parked two streets away." "It's called atmosphere, Bill." He squinted at the map. "You've drawn seventeen different unicorns on this." "They're decorative. Now focus. The presents are stacked by the garden fence, which means extraction should take under four minutes." Bill scratched his chin thoughtfully. "What if some kid sees us?" "Children at parties are completely feral. Nobody will notice two adults walking out with gift bags." "I'm wearing a hi-vis jacket." "Exactly. We're invisible." A balloon drifted over the fence and bounced gently off Bill's head. They both watched it float away in silence. "Molly," Bill said slowly, "these are six year olds." "Rich six year olds." "That doesn't make it better." "One of them is getting a puppy, Bill. A living puppy as a present." Bill grabbed his end of the empty sack. "Alright," he sighed. "But we're leaving the puppy."
