Molly pressed her back against the minivan, binoculars trained on the bouncing castle. Bill unfolded the blueprint of the community center with exaggerated care. The sun glinted off wrapping paper visible through the glass doors, a mountain of boxes guarded only by parents. A banner reading HAPPY 5TH BIRTHDAY LEO flapped above the entrance. "You see the clown?" Molly whispered. "I see a six-foot liability with a balloon sword," Bill replied. "We go through the kitchen during cake time," Molly said. "Stealing presents from six-year-olds feels low, even for us," Bill muttered. "They're untouched Lego sets worth four hundred each," Molly hissed. Bill stared at the driveway cluttered with tiny sneakers and tricycles. "So what's the signal?" Bill asked. "When they sing happy birthday, we crawl through the side window," Molly said. "What if they notice two adults in ski masks grabbing Bluey gift bags?" Bill asked. "Then we pretend we're the entertainment," Molly said. "And no stealing the cake again," Bill said. "I promise, unless it's chocolate," Molly laughed. "Yes dear," Molly said. Bill sighed and pulled his mask down. "Fine, but I'm not popping balloons," Bill grumbled. "Deal, just grab the pile by the bounce house," Molly whispered.
