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, explain again why we’re robbing a birthday party.” “Because, Molly, nobody guards a bouncy castle with the seriousness it deserves.” “They’re children’s presents.” “Unopened children’s presents. Could be jewelry.” “Could be socks with dinosaurs.” “Dinosaurs are valuable in bulk.” “You said this was a high-end target.” “It is. The invitation had glitter.” “Glitter is not financial intelligence.” “It stuck to my elbow for three days. That’s commitment.” “What’s the entry plan?” “We arrive disguised as entertainers.” “Please tell me you didn’t book us as clowns.” “Of course not. Clowns attract scrutiny.” “Good.” “We’re balloon magicians.” “Bill.” “I learned a dog.” “That is not a complete act.” “It’s a loyal beginning.” “And while you’re twisting rubber mammals, I do what?” “You mingle near the gift table and deploy the decoy.” “The decoy?” “A piñata labeled ‘Free Candy.’” “At a children’s party? That’s not a decoy, that’s a riot.” “Exactly. Chaos, shrieking, frosting everywhere.” “You’ve planned this like a man banned from six bakeries.” “Seven, pending appeal.” “Masks?” “Party hats.” “Getaway?” “Ice-cream truck.” “You stole an ice-cream truck?” “Borrowed. It plays ‘Greensleeves’ menacingly.” “Molly, Bill,” called a small voice from behind them, “Mom says you’re late.” They froze. Bill whispered, “Abort?” Molly sighed. “Bring the balloon dog.”
