"So we just walk in?" Molly asked. "Through the front door. Confidence is key." "Bill, it's a six-year-old's birthday party." "Exactly. Nobody suspects adults at a kid's party." "Everyone suspects adults at a kid's party. That's literally how parties work." "We'll bring a gift. Blend in." "We're stealing the gifts. Why would we bring one?" "Camouflage, Molly. You bring a gift, you take forty gifts. It's basic mathematics." "That's not mathematics. That's just stealing with extra steps." "What's the plan once we're inside?" "You distract them. Do a magic show." "I don't know any magic." "You pulled a wallet out of a stranger's pocket yesterday." "That's pickpocketing, not magic!" "To a six-year-old, what's the difference?" "And what'll you be doing during my so-called magic show?" "Loading presents into the bouncy castle." "You're going to steal the bouncy castle?" "It inflates, Bill. It's basically a getaway balloon." "That's the dumbest thing I've ever heard." "Coming from the man bringing a gift to a robbery." "Fine. What do we get the kid?" "Nothing expensive. We're taking it back anyway." "A re-gifted regret. How festive." "Just smile, wave, and follow my lead." "Molly?" "What?" "There's clowns. I hate clowns." "Then steal faster."
