Molly parked the getaway tricycle behind the bakery, its bell taped shut and its basket stuffed with disguises for tonight's operation of festive larceny downtown. “Bill, remember: we enter through the birthday clown’s inflatable pants, grab every gift, and leave before anyone notices the cake is humming in suspicious harmony.” Bill adjusted his pirate hat, concealing neither beard nor wanted poster. Across the street, balloons bobbed like nervous witnesses above the party house, awaiting their raid. “Relax. I’ve mapped the nursery, bribed the clown, and trained the dog to bark only when somebody says ‘taxes’ with proper emphasis very loudly indeed.” Molly unfolded a blueprint drawn on a napkin. It showed three doors, a moat, and a remarkably judgmental cupcake wearing a tiny crown in crayon. “Excellent. I’ll distract the parents with my award-winning puppet routine. You fill the sack. If questioned, we’re emotionally supportive uncles from the gift registry department.” At the gate, Molly paused as a small girl approached, clutching a plush dragon and wearing detective glasses bright enough to expose them both immediately. “New plan, Bill: we’re not stealing presents; we’re rescuing them from gravity. Please point us toward the nearest emergency gift basket with wheels, preferably quickly.”
