Molly unfolded the invitation like a treasure map, though it was sticky with jam and glitter. Across the café table, Bill peered over his fake mustache, which had begun migrating toward his chin. The party was at noon, in a church hall guarded by one balloon clown, three grandmothers, and a Labrador with frosting on its ears. Their target: a mountain of wrapped presents, each one probably containing batteries, robots, or socks masquerading as disappointment. Molly tapped the address with a teaspoon. "Bill, enter as magicians, distract parents, vanish with loot cleanly." Bill frowned, counting imaginary doves in his pockets. "Molly, my only trick escaped, and it owes me money." They sat in solemn silence while a toddler at the next table loudly robbed a muffin. Molly sketched escape routes through musical chairs, pass-the-parcel, and the hazardous jelly zone. Bill suggested tunneling, then remembered his fear of worms. By dessert, their plan had improved: arrive with a giant empty gift box, hide inside, and wait. Unfortunately, the invitation clearly said Bring a present. Molly sighed. Bill ordered cake, for research. Outside, rain polished the pavement, and somewhere a child laughed, unknowingly defending a fortress of ribbon bows and tissue paper.
