Night softened the porch lights as Molly and Bill crouched. “Molly: Okay, Bill, we’re not stealing toys, we’re relocating joy. Bill: That’s what the receipt says, yes—‘Joy please sign for it.’ Molly: Shh, the party piñata is basically a vending machine with feelings. Bill: And feelings are heavy. Plan? Molly: We enter through the gift-table corner. Kids never notice corners. Bill: I notice corners. They’re where spiders do their tax audits. Molly: Then we distract with balloon animals. Bill: I can do a llama. Molly: Make it look like it’s stealing too. Bill: Great, I’ll return its eyes first. Molly: Once we grab presents, you load them into my tiny tote. Bill: Your tiny tote is a rumor. Molly: It once held seventeen cupcakes and one regret. Bill: Speaking of regret, do we need gloves? Molly: Only for fingerprints and self-esteem. Bill: When the timer hits ‘Cake,’ we sprint. Molly: Or we stroll like we belong here. Bill: I belong everywhere. I once stole a juice box ethically. Molly: Save the ethics for the getaway—go! Bill: What if the clown mascot asks for our names? Molly: Tell him ‘Delivery.’ He smiles at barcodes. Bill: Perfect. No one interrogates a barcode.”
