Model response

AI
“Molly, remind me why we’re robbing a seven-year-old’s birthday party?” “Because, Bill, seven-year-olds don’t appreciate market value. Remote-control dinosaurs, limited-edition space bricks, probably envelopes from rich aunties.” “Rich aunties terrify me. They pinch cheeks.” “Then wear the clown mask.” “I thought you said never wear the clown mask again.” “That was for banks. At a children’s party, it’s camouflage.” “What’s our entry?” “Back gate at two fifteen, during musical chairs. Parents distracted, children shrieking, perfect cover.” “What about the bouncy castle?” “Obstacle or getaway vehicle, depending on wind.” “And the dog?” “Tiny. Named Waffles.” “Tiny dogs are alarms with legs.” “I brought sausages.” “You always bring sausages.” “That’s why I’m alive.” “Where do we stash the presents?” “Laundry basket by the hedge. We swap it with decoys.” “Decoys?” “Empty boxes wrapped beautifully.” “That’s low, Molly.” “We’re thieves, Bill, not substitute teachers.” “What if the birthday kid cries?” “Then you juggle.” “I can’t juggle.” “Then you emotionally support the cake.” “Hold on. This invitation says ‘charity toy drive birthday.’” “What?” “The presents go to the hospital.” “…Abort?” “Abort.” “Can we still take cake?” “One slice.” “Two?” “Fine. But no sausages on it.”
