Model response

Molly crouched beside the tool cart, whispering to her lock picks like they were shy animals. Bill hovered near the frosting table, pretending to examine the balloons while he scanned the room through a crack in the doorway. From inside, the party thumped with cheerful music and the sharp laughter of children who still believed in fairies and cake. “We are in and out,” Molly mouthed, then checked her timer twice, as if time might sense her intentions. Bill adjusted his cap and offered a grin that looked practiced. “You picked the slowest birthday theme on purpose,” he said. “Dinosaurs are never slow,” Molly replied. She slid a slim card into the side of the doorframe and listened for the tiny click that meant permission, or at least the illusion of it. A security camera pivoted overhead, its red light blinking like a bored eye. Bill raised a finger. “When it blinks, we move. Simple.” “Simple is a lie,” Molly said, but her hand already drifted to her pouch. The camera blinked. The door sighed open. They slipped into the hall where presents stacked like candy-colored treasure chests. Bill reached for a tag, then paused. “What if the kids named them?” he asked. Molly plucked a ribbon free and muttered, “Then we steal the names too.”
