"Are you entirely sure the plastic bounce house is secure?" Molly whispered carefully, adjusting her tactical goggles from the bushes. "I tied the main generator cable to a sleeping dog," Bill replied softly, stuffing his deep pockets with uninflated balloons. "That absolutely does not sound like a reliable defensive perimeter," she sighed heavily, unrolling a sticky map covering the backyard. "Listen, once the clown starts juggling, we hit the target." He pointed a dramatic finger toward the massive patio table. "You seriously mean the towering mountain of wrapped birthday presents?" Molly gulped loudly, nervously watching the screaming toddlers running around. "Exactly. I will distract the exhausted mothers with terrible gossip." Bill smiled calmly, firmly gripping a thick nylon climbing rope. "You creep past the juice boxes and secure that tricycle." A crying child ran quickly past them holding a cupcake. "What if the highly hyperactive birthday boy suddenly catches me?" she muttered quietly, readying her grappling hook for the mission. "Throw a handful of glitter at his face and run," Bill whispered confidently, checking the time on his plastic watch. "This is why you are my favorite professional party burglar." They stepped out from the shadows and began the heist.
