Molly: Bill, the children's party starts at dusk; timing matters. Bill: Relax, partner. We'll glide in like overdue party favors. Molly: We need distraction: a magician's hat, confetti, and misdirection. Bill: Confetti distraction. Got it. Also a cake with candles. Molly: Do not burn the plan; carry silent, squeaky bags. Bill: Silent bags. Got it. Quiet trolleys, no squeaks, screams. Molly: Presents are in the hall closet behind puppet show. Bill: Puppet show? Perfect cover for heavy lifting and snacks. Molly: We’ll swap tags, no receipts, only giggles and glitter. Bill: Glitter is risky; it sticks to fingers and dreams. They circled the edge of the neighborhood, trading whispers like lunch money and secrets. A balloon arch hummed overhead, and a drumbeat of distant laughter stitched the street together. Molly checked a tote labeled Fragile Enchantments, Bill tested a glove that doubled as a slapstick gadget. The plan unfurled in their minds: blend with the clinking of plastic cups, slip past the sniffling dog, vanish into the glow of party lights, load bags with color-wrapped treasure, exit through the kitchen window, leave a trail of confetti behind like breadcrumbs for the night. Their laughter echoed softly as the street listened.
