Model response

Molly crouched beside the cupcake table, listening to squeals like alarms. “Do we really have to knock?” she whispered. Bill unfolded a laminated map labeled BEDROOM WIZARDRY. “Not unless you want the clown to file charges,” he said. From the hallway came the party host: “Okay kids, countdown to the piñata!” Molly’s eyes widened. “Countdown? Great, we’re stealing on a schedule.” Bill slid a tiny crowbar into a gift-wrap seam. “Steal the presents, not the kids’ hearts,” he muttered. Molly giggled. “Too late. I already feel emotionally attached to the toy dinosaur.” Bill glanced at the door. “Keep talking and the security penguin might hear you.” Molly held up a bag the size of a laundromat. “I’ve got a vacuum-seal plan. We’ll be out before frosting becomes evidence.” A chorus of children bounced past, singing, “It’s your birthday, it’s your birthday.” Molly flinched. “If they’re that happy, why are the presents so guarded?” Bill shrugged. “Because parents are just squirrels with credit cards.” The latch clicked. “Step one,” Molly said, grinning. “Steal the presents.” Bill nodded. “Step two: run like we’re escaping a birthday lawsuit.” They sprang into the room, and the whole tree of wrapped boxes wobble-laughed for science.
