Model response

AI
“Molly, it’s a children’s party, not Fort Knox.” “Bill, Fort Knox never had a bouncy castle blocking the west entrance.” “You’re seriously calling the inflatable dinosaur an entrance hazard?” “It has teeth, doesn’t it?” “It’s full of air.” “So are you, but I still plan around you.” “Fine. What’s the target?” “The present table. Pink cloth, glitter banner, suspiciously strong grandmother guarding it.” “Grandmothers don’t guard. They hover.” “This one has a handbag shaped like a brick and eyes like courtroom evidence.” “Plan?” “We arrive as entertainers.” “I am not wearing the clown trousers again.” “You stretched them.” “They were mislabeled.” “They said ‘ages six to eight.’” “Exactly. Very misleading.” “I’ll be the magician. You’re my assistant.” “Why am I always the assistant?” “Because last time you said ‘abracadabra’ and sneezed into a pigeon.” “It startled me first.” “Focus. At cake time, everyone sings. We wheel the presents out under the fake rabbit hutch.” “What about the children?” “Distracted by frosting.” “What about the parents?” “Distracted by filming frosting.” “What about the grandmother?” “You compliment her potato salad.” “Dangerous. What if it’s bad?” “Bill, for twelve wrapped boxes, you will lie.” “I’ll need hazard pay.” “You’ll get a party bag.” “With bubbles?” “If you behave.” “Deal.”
