Model response

AI
Molly peered through the bakery window at the riot of balloons next door, where a clown stumbled past a cardboard castle and three mothers argued over napkins. She adjusted her black gloves with priestly solemnity. “Bill, this is our Sistine Chapel.” “It’s a village hall full of juice boxes.” “A treasure vault wrapped in cartoon paper,” Molly whispered. “Observe the terrain.” Bill squinted. “Bouncy castle at six o’clock. Sugar-crazed minors everywhere. One magician, possibly armed.” “We go in disguised as entertainers.” “You can’t juggle.” “I can lie confidently while dropping things.” Bill tugged his cap lower. “What about the presents?” “Table by the cake. We create a diversion, seize the loot, and vanish before the candles are lit.” “That’s your plan? Chaos and speed?” “That is every good plan.” Inside, a shriek rose as a child walloped the clown with a foam sword. Bill winced. “Hostile security.” Molly grinned. “Amateur security. Sticky, loud, and easily bribed with sherbet.” “With what money?” “We use their money. Check the birthday cards.” Bill stared. “That’s despicable.” “That,” Molly said, straightening her jacket, “is layered criminal thinking.” A woman emerged carrying a tray of cupcakes. Bill inhaled. “New plan. We steal one present and six cakes.” Molly considered it gravely. “At last, the voice of professionalism.”
