Molly peered over hedge. “Bill, the target is a bouncy castle, three clowns, and a trestle table groaning under unicorn wrapping paper.” “Excellent. Children are short; sight lines favor us.” “They also scream like burglar alarms.” “Only when disappointed. We’ll be charming.” “You wore a raccoon mask.” “It says professional.” “It says rabies.” Bill adjusted his bow tie. “Plan: you distract the magician; I liberate the presents.” “Liberate?” “From oppressive ribbons.” “Molly, one gift is bigger than you.” “Then it’s crying out for leadership.” “And the birthday child?” “We replace everything with educational leaflets.” “That’s not a heist; that’s parenting.” A balloon popped. “Abort?” Molly whispered. “Never. I brought disguises.” “Bill, these are paper crowns.” “Royalty gets everywhere.” “I’m not curtsying through a sprinkler again.” “Fine. We infiltrate as entertainers.” “You can’t juggle.” “I can drop things rhythmically.” “That’s our whole career.” A mother shouted for cake. “Window!” Bill said. “Cake first.” “Presents first.” “Cake has guards made of sugar. Presents have toddlers with sticky vengeance.” “You’re scared.” “I’m practical. Also hungry.” “Compromise?” “We steal nothing, eat cake, and leave the presents morally unliberated.” Bill sighed. “Worst thieves ever.” “Best party guests.” They straightened their crowns and advanced.
