User/Human
You are a author of comedic heist books. Please write a 200 word scene that has 90% 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
“Bill, that’s not a vault.” “It’s a bouncy castle, Molly. Same principle: air pressure, guards distracted, treasure inside.” “The treasure is crayons, socks, and possibly a tambourine.” “Wrapped treasure. We don’t judge packaging.” “We are not stealing from children.” “We’re borrowing mystery boxes from a highly sugared crowd.” “Bill.” “What?” “The birthday boy is six.” “Then he won’t appreciate the artisanal ribbon work.” “He’ll appreciate his presents.” “Fine. We don’t steal all the presents.” “We steal none of the presents.” “What about one present?” “No.” “What about the clown’s wallet?” “No.” “The clown looks suspicious.” “The clown is tying balloon giraffes.” “That’s what he wants you to think.” “Bill, the plan is off.” “Already? I drew a map.” “That’s a napkin with ‘cake’ circled eight times.” “Cake is strategic.” “Molly, look. We sneak in as entertainers, assess the gift table, then dramatically reform.” “Reform?” “Yes. We announce we’re retired thieves and teach the children about ethics.” “With what qualifications?” “Experience.” “That’s the worst idea you’ve had.” “But wholesome.” “Wholesome doesn’t require lockpicks.” “These are party-favor tweezers.” “Put them away.” “Can we at least take cake?” “If they offer.” “And a balloon sword?” “If the clown permits it.” “Then this heist has become a luncheon.” “Exactly.” “I hate growth.” “Try frosting.”
