The kitchen smelled of lemon rind and broken party hats. Molly checked the clock, tapping a silver spoon against the counter. Bill eyed the storefront window, pretending the chandelier was a lighthouse. They spoke in low, ridiculous whispers, like villains auditioning for a school play. A cardboard cake grin watched them from the table, its candles extinguished long ago by dust. Outside, a faint siren of laughter bubbled from the party, not danger, only sugar and squeals. They rehearsed their plan as if stealing presents required etiquette, not speed. Molly grinned; Bill cracked his knuckles with comic solemnity for stagecraft. "Molly: Quiet now, the gumdrops aren't dangerous; they just won't forgive a sneeze." "Bill: We enter through the squeaky gate, wave the banner of birthday wishes, and vanish." "Molly: I mapped the path with stickers and glitter, so the security guard follows glitter, not footprints." "Bill: Brilliant strategy, though the cake will scream when we lift the lid." "Molly: If anyone notices, we improvise with balloon animals and a heroic squeal." "Bill: Agreed, we grab the biggest pile, swap it for a smaller, peppier pile later." "Molly: If someone notices, we improvise with balloons and a heroic, ridiculous exit tonight."
