Model response

AI
Molly unrolled a crayon drawing of the backyard across the hood of the van. "Okay, Bill, run it back. What's the target?" "Timmy Henderson's seventh birthday. Two o'clock. Bouncy castle, magician, forty-two presents." "Forty-two? You counted?" "I've been in the hedge since Tuesday, Molly." Molly sighed. "Fine. Entry point?" "We go in as clowns. Nobody questions a clown." "Everybody questions a clown. That's the whole thing about clowns." "Then we go in as the magician." "There's already a magician." "Then we make him disappear." "Bill, we're not whacking a magician." "I meant with a trick! I've been practicing the scarf one." "You can't do the scarf one." "I can do the scarf one." "You pulled a scarf out of your sleeve and it was my scarf. You stole my scarf to practice." Bill adjusted his rubber nose. "That's commitment." "Getaway?" "Pony rides. Slow, but untraceable." "And the kids?" "Distracted by cake. Seven-year-olds see cake, they go feral. We've got four minutes, tops." "And if Timmy notices?" "Timmy won't notice." "Why not?" "Because I'm bringing him a present too." "You're bringing a present to the party we're robbing?" "It's rude not to, Molly."
