Molly crouched behind the hedge, wearing a burglar's mask and a paper crown. Bill unfolded a map of the community hall: a giraffe drawn in crayon. Inside, children shrieked around a magician, and ribboned boxes glittered beside the cake. “Molly, this plan has a tiny flaw.” “Only one?” “We're stealing from six-year-olds.” “Temporarily borrowing, Bill. We'll ransom teddy bears for biscuits.” “The sign says charity party.” “Then we'll steal only the loud presents.” “How do you identify a loud present?” “If it rattles, honks, or says batteries included, it's coming with us.” Bill peered over the hedge. A toddler stared back, holding a balloon sword. “I think we've been spotted.” “By security?” “Worse. A pirate princess.” Molly adjusted her crown. “Then we negotiate.” Before they could move, the magician announced volunteers. The toddler pointed. Twenty children turned toward the hedge. Bill sighed, produced two wrapped boxes from his coat, and whispered, “Retreat?” “Not yet. Smile like generous uncles.” “You're not my niece.” “Bill, focus.” “Reverse heist. Leave presents, take cake.” “And the biscuits?” “Only if they offer.” “They're offering glitter.” “Run politely.” “Very politely.” Molly nodded. They marched in smiling, defeated by hospitality, frosting, and suspiciously sticky hands at once.
