Model response

Molly studied the suburban garden from behind a hedge shaped like a confused dolphin. Balloons bobbed over the fence, and somewhere beyond it a clown honked with the grim authority of a tugboat. “Tell me again,” Bill whispered, adjusting the tiny party hat he insisted was camouflage, “why we’re robbing a birthday instead of a bank?” “Because banks have guards, cameras, and consequences,” Molly said. “Children have cake.” “Children also have parents.” “Distracted parents. Sugar-drunk, sunburned, emotionally exhausted parents.” Bill peered through the leaves. “There’s a magician.” “Excellent. Nothing hides theft like mediocre magic.” “I still think this is low.” Molly checked her watch. “Morally, yes. Financially, surprisingly promising. Look at those gift bags. That one’s definitely remote control car-shaped.” “What if they catch us?” “Then cry and say we’re estranged cousins.” Bill frowned. “I can’t cry on command.” “Think about taxes.” A roar went up from the garden. The clown had apparently fallen into the paddling pool. “Window,” Molly said. “Open,” Bill said, easing the side gate. “Smell that? Icing and opportunity.” They slipped inside, weaving between pirate banners and a table sagging under sausage rolls. Molly reached the present pile like a pilgrim at a shrine. “Grab and grin,” she murmured. Bill hefted a glittery box. “Happy birthday to us.” Behind them, a child’s voice rang out. “Mum, why are those adults stealing my dinosaur?”
