Model response

AI
Molly and Bill crouched behind the birthday balloons. “Bill, quiet. We’re stealing the good stuff from the kids’ party.” “Quiet? The bounce house is louder than my childhood.” “Exactly—blend in. You’re wearing the llama hat; I’m the polite balloon cloud.” “You can’t be a balloon cloud. You’re a woman with plans.” “Plans are balloons. Inflate them with theft.” “Uh-oh. Host’s dad just yelled, ‘Anyone have allergies?’” “We do. Allergies to boring decorations.” “I brought the present sack.” “Name it something cute so you don’t sound like a criminal in line: ‘Giggle Bag.’” “Giggle Bag it is. What’s the target?” “Every gift under the table, plus the ones people ‘ooh’ at.” “And the unwrapped pile?” “Only if it’s still wrapped in its innocence.” “How do we grab them without triggering the toy-inator?” “We use the distraction: you spill punch.” “I can’t spill punch. I’m a professional.” “Perfect. Spill it professionally.” “On three?” “On three. One—walk like we belong. Two—smile. Three—steal, then exit as gently as a kindergarten fart.” “What about the magician? I stole from a circus; the rabbit filed a complaint.” “No rabbits today. Only toddlers. If anyone asks, we’re ‘party helpers’ with wishes.” “And if the presents start screaming?” “Then you whisper, ‘Be brave, it’s a nap.’”
