Rain tapped against the abandoned bakery where Molly and Bill studied a sketched map of the party venue. Molly said. “We enter disguised as balloon artists when the clown arrives.” “And the presents? I hope children appreciate silent, temporary ownership.” “We grab boxes, especially anything wrapped in glitter or guilt.” “The getaway is Aunt’s van, parked beside the inflatable castle.” “What if someone asks why our balloon animal has pockets?” “Tell them it is modern, distract them with jazz hands.” Bill adjusted his borrowed bowler hat, which contained three lockpicks and one emergency sandwich. Outside, painted balloons bobbed above a suburban garden, while children shrieked around a magician dressed as a nervous rabbit. Molly circled the delivery entrance with red pencil. Bill inspected their equipment: two sacks, a ladder, disguises, and a remarkably convincing plastic mustache. The plan depended on timing, confidence, and nobody noticing the sacks. At noon, Molly tucked the map away. Bill practiced smiling innocently. “I deeply dislike children’s parties; the frosting always leaves evidence.” “Wear gloves, Bill. Last time, you personally fingerprinted a cupcake.” “That cupcake looked suspicious, and I panicked professionally under pressure.” “Focus. We steal presents, not snacks, children, or the entertainment.”
