Molly pressed her ear against the community center door, listening to off-key singing inside. Bill crouched beside the gift table window, binoculars fogged from his breath. "This is humiliating," Molly whispered. "We're cathedral thieves stealing Bluey paper?" "Hey, that mountain of presents is worth three grand," Bill whispered back. "My cousin said that kid gets spoiled rotten." "The invites said laser tag and cake," Molly said. "We can just walk in dressed as clowns." "We hate children," Bill said. "And we hate clowns even more." "Fine, we cut the power during the blackout," Molly replied. "You distract the parents." "I don't know how to make balloon animals," Bill protested. "I'll just pop them loudly instead." Molly sighed and zipped open her duffel bag full of empty sacks. She tossed him a red nose that squeaked pathetically when he caught it. He stared at it with existential dread as children's laughter erupted inside. "Do I have to wear this?" Bill asked. "I look like my disappointed father." "Yes, you look beautifully tragic," Molly answered. "Now smile before we steal childhood itself." The bouncy castle wheezed loudly beside them, smelling faintly of juice boxes and impending felony charges while parents sang obliviously.
