Molly crouched behind the birthday clown's rented van, peering through the hedge at the backyard party. "Right, Bill. Eight kids, one bouncy castle, and a mountain of presents. Our window's the cake cutting." Bill adjusted his fake mustache. "Why the cake cutting?" "Because every child in England stares at cake like it's the Second Coming. Nobody watches the gift table." "And the sack?" "Lumpy, enormous, and it smells like crisps. Perfect." She tapped her clipboard. "Dibs on the Lego sets. Those sell for a fortune." Bill frowned. "Molly, there's a toddler on the swing set. He's eyeing us." "Wave at him. Look friendly." Bill waved. The toddler screamed and bolted for his mother. "Brilliant," Molly hissed. "Now they'll know we're here." "Relax. Nobody believes a toddler." Dialogue words account for roughly half of the scene, with the remainder as narration.
