In the dim glow of a storage room behind the bakery, Molly unfurled a map drawn on parchment sacks of flour. Bill adjusted his cap as if he were auditioning for a silent film about petty larceny in a circus. The air smelled of vanilla cupcakes and old sneakers, an odd perfume for a caper. They spoke in whispers that sounded like accordion frogs, careful not to wake the clock at the end of the hall. "We crash the party, grab the gifts, no questions." "Quiet, first corner, then upstairs vault." "Plan's deliciously silly." "Shhh, timing." Molly traced a finger along the route with a dramatic flourish, as if the line might lead to a treasure chest of oversized bouncy balls. Bill checked the imaginary security film by tapping a kettle lid like a gavel. Overhead, a poster of a field trip to a dinosaur museum flapped in a draft, as if applauding their plan. They rehearsed their exit with the gravity of two toddlers plotting a parade float theft, giggling at the mere thought of wrapping the world in gift wrap and bows. Finally, Molly winked. Bill shrugged. The heist, harmless in their heads, began feeling like a party.
