Molly crouched behind the hydrangeas, studying the inflatable castle as it sagged and wheezed like a dragon with hay fever. Bill balanced a clipboard on his knee, wearing a clown nose he called tactical. Across the lawn, toddlers orbited a mountain of packages beside a dinosaur cake and juice boxes. “Molly, remind me why we are robbing six-year-olds?” “Because six-year-olds have grandparents, Bill. Grandparents buy recklessly. Look at that ribbon. That is retirement-grade ribbon.” “I feel judged by the balloon giraffe.” “Focus. At noon, the magician releases doves. We mingle, grab sacks, exit through beanbag toss.” “Your plan depends on birds, toddlers, and my ability to mingle.” “Exactly. No one expects competence.” “What if a child cries?” “Bill, they cry when socks exist.” “What if their parents chase us?” “Then you juggle. I vanish.” “I cannot juggle.” “That is why they will chase you.” “Brilliant and hurtful.” “Mostly brilliant.” “Fine.” A shriek rose as the magician produced one exhausted pigeon. It flapped into the cake, frosting the dinosaur’s face with shame. Parents ran. Children cheered. Bill stood, tripped on his enormous shoes, and rolled into the gifts. Molly watched applause swallow him, bowed grandly, and reconsidered larceny for recipes tonight.
