You are a author of comedic heist books. Please write a 200 word scene that has 50% words of dialogue between two thieves named Molly and Bill who are planning to break into a children's party to steal all the presents. Only include the prose of the scene without any markdown or commentary.

Model response

AI
Molly crouched behind the garden wall, studying balloons bobbing above the hedge like colorful alarms. Bill adjusted his flat cap and peered at the house, where shrieks of sugar-fueled children burst through the open windows. “Tell me again,” Bill whispered, “why we’re robbing a birthday party instead of a bank?” “Because,” Molly said, “banks have guards, cameras, and adults. This place has a clown and a bouncy castle.” “I fear clowns more than prison.” “Keep your nerve. Presents are stacked by the patio doors. We go in as entertainers, lift the lot, and vanish before cake.” Bill eyed her feathered hat. “Entertainers? You look like a flamingo who’s fallen on hard times.” “And you,” said Molly, straightening his bow tie, “look like a magician banned from three counties.” From inside came a chorus of children chanting for balloons. Bill swallowed. “What if they ask for a trick?” “You smile, wave your wand, and say, ‘For my next illusion, I shall make your gifts disappear.’” “That’s less a trick and more a confession.” Molly grinned, producing a sack from under her coat. “Ready?” Bill sighed. “No. But I wasn’t ready for adulthood either.” They hopped the wall together, landing beside a cardboard pirate. Somewhere inside, a clown honked, and Bill nearly fled.
