Model response

Molly crouched behind the hedge in a glittery raccoon mask, watching balloons bob beyond the church hall windows. Bill unfolded a frosting-spotted napkin labeled MASTER PLAN, upside down. Inside, children shrieked while a magician produced a disappointed dove. “Right, Bill, we enter with dignity, locate the gift table, and leave richer by twelve stuffed unicorns.” “Fourteen, Molly. I counted during the hokey pokey while maintaining criminal mystique.” “You joined the hokey pokey?” “Only as research. Also, they had tambourines, juice boxes, and suspiciously good cheese cubes.” “You wore a paper crown.” “Every king needs cover, Molly, especially near a bouncy castle full of witnesses.” A tiny girl burst outside chasing a runaway hat. She stared, then offered Molly a cupcake with tragic seriousness. Molly accepted. Bill blinked suspiciously fast. The birthday song wobbled through the wall like a guilty conscience. “Bill, new plan.” “Excellent. Smoke bomb, grappling hook, or trained ferret with tiny boots?” “No. We sneak in, add presents, and steal cake.” “Cake isn’t theft if destiny cuts it into slices. Big slices.” They marched in carrying two wrapped bricks and smiles. Ten minutes later, Molly wore a princess sash, Bill danced with Grandma, and every present remained unstolen.
