Model response

Bill tiptoed behind the gift table, pretending the duct-taped shopping bag was “merchandise.” Molly hovered near the inflatable slide, where cheerful balloons bobbed like clueless guardians. The children were already giggling at face-paint stations, their joy echoing through the living room. Molly lowered her voice anyway, because thieves have standards. Bill checked the hallway for parents, then checked again, because panic is its own cardio. “Molly,” Bill whispered, “are we stealing everything?” “Everything that’s shiny,” Molly whispered back, “even the boring boxes.” Bill reached for a bow-tied parcel. “What about the ones labeled ‘Do Not Open’?” “Those are obviously instructions,” Molly said. “We follow them by opening them.” Bill glanced toward the kitchen. “And the backup plan?” “We don’t need a backup plan,” Molly said. “We’re adorable.” “That’s not a plan,” Bill muttered. “It’s a disguise,” Molly corrected. “Kids trust cuteness. Parents trust paperwork. I have neither.” Bill swallowed. “Okay. After we grab presents, we leave… what?” “Glitter,” Molly said, grinning. “So the mess looks festive, not criminal.” Bill nodded, then hesitated at the stack of wrapped boxes. “What if one’s actually for us?” Molly clapped once, sharply. “Then we steal it faster.” Bill and Molly moved in sync, snatching joy with the confidence of people who definitely hadn’t read the rules.
