“Molly, say the words and don’t laugh—what’s our plan?” “We’re going to the children’s party, Bill, and we’re stealing every single present. Quietly. Elegantly. Like professional adults in matching hoodies.” “Matching hoodies? You think we’re going for ‘mysterious’ or ‘the costume aisle’?” “Mysterious. Obviously. I have a diversion.” “You always have a diversion. Last time it was a squeaky toy.” “That squeaky toy saved us. Also, it was technically a tool.” “Fine. We enter how?” “Through the side gate, using the universal key we definitely didn’t steal from your bicycle—” “Hey, that key was already missing. The bicycle just… moved on.” “We’re not discussing your moral philosophy. When the door opens, you say, ‘Is this where the treasure is?’” “That’s creepy for a party full of toddlers.” “It’s funny creepy. Like a magician who respects nap schedules.” “Okay. What about the parents?” “Bill, we’re wearing fake mustaches.” “I don’t see how that hides our crime face.” “It doesn’t hide it. It decorates it.” “Bells on the gift table?” “Lights off, hands steady. You grab the big ones.” “What if the big ones scream?” “Then we admire their enthusiasm and keep collecting.” “Molly, you’re terrifying.” “Thank you. Now—remember: no one leaves empty-handed.” “Except the children.” “Exactly. Let’s go, silent professional professionals.”
