Model response

Molly unfolded a napkin covered in arrows. "Bill, the magician sprained his wrist in a ball pit, so tonight we're sneaking in as Marvello and his glamorous assistant." Molly tossed him a sequined waistcoat. "Why am I the glamorous one?" "Because you're wearing sequins. Kids can smell fear, so look confident." "And the trick?" "The Vanishing Presents. You wave the wand, I sweep every present into the sack, and nobody notices because they're screaming at the bouncy castle." "What about the little one with the plastic sword?" "Dylan. Six years old, bit his own dad at Christmas. Give him a balloon sword and an extra slice of cake." "Isn't that bribery?" "Crime's mostly bribery, Bill." "And the mum?" "Julia? Gin and a clipboard. Never underestimate a clipboard." Bill's conscience stirred beneath his sequins. "Molly, they're only little." "They've got enough Lego for a second house. They'll survive." "Fine. And the exit?" "Out the back, past the bins. Nobody watches the bins." "And the getaway van?" "Parked behind the bouncy castle." "Why there?" "Nobody looks behind bouncy castles." "And if we get caught?" "We say it was part of the act." "Will they buy that?" "They're six, Bill. They'll believe anything with jazz hands."
