Molly peered through the fence at the backyard where toddlers screamed around a pile of presents. Bill checked his watch and sweated beside her. "Molly, are we really robbing a five-year-old's birthday?" Bill whispered, his voice cracking. "Those presents are untouched, Bill. It's a victimless crime. Mostly victimless," Molly replied, adjusting her ski mask. "That cake says Happy Birthday Timmy. Timmy will cry," Bill said, pointing at the frosting. "Timmy has enough Legos. We have rent due. Focus," Molly snapped, unfolding the floor plan. "What's the plan then? Clown distraction again?" Bill asked, pulling a nose from his pocket. "You dress as the clown, I grab the loot through the kitchen," Molly said firmly. "What if the kids love me? What if I love them?" Bill wondered aloud, sentimental. "Then you balloon animals until I honk. We vanish. Simple," Molly whispered, rolling her eyes. "Bill, stop bonding now. Grab the presents and run very fast," Molly hissed urgently. "But Timmy's mom baked cookies. Can we please take extra cookies too?" Bill begged hungrily. Bill nodded, inflating his courage along with a giraffe, while Molly slipped toward the gate as music started. The clown music grew louder and parents clapped nearby.
