Bill, the inflatable giraffe blocks the window, Molly whispered. “No problem, we’re smaller than giraffes.” She slid a sticker map of the house from her pocket. “You sure it’s a kids’ party?” Bill grinned. “Molly, I read the invitation. It says ‘bring a gift and unleash joy.’ We brought masks and reduced joy.” Molly crouched by the shrub. “Plan: we go in quiet, steal only presents, and leave the cake untouched.” “Cake tastes like homework,” Bill said. “Fine. Present theft only. But we need the good loot.” Molly pointed at a pile of wrapped boxes. “Those are for ages three through eight.” Bill nodded. “Perfect. We’re not above stealing from minions of cardboard.” Molly checked her timer. “On my mark, we open the gift table, snatch, and zip out.” “What if someone yells ‘Merry Christmas’ like a security alarm?” Bill asked. Molly smirked. “Then we shout, ‘Happy Birthday to the concept of theft!’” Bill paused. “You can’t say that.” “I just did,” Molly replied. They crept toward the living room, where laughter floated like frosting. Bill whispered, “Remember: no sticking our hands in the glitter.” Molly breathed, “Agreed. Glitter has a restraining order.” Their disguises squeaked, but the music masked it perfectly.
