The rented minivan coughed to a stop at the curb like it had been bribed with stale coupons. Molly adjusted her striped beanie and nudged Bill under the porch light. Beyond the windows, a disco ball rotated like it was searching for evidence of joy. Bill whispered, “If we get caught, I’m blaming your hat. It looks guilty.” Molly grinned. “My hat is innocent. Your face looks like a used mop.” Bill checked the shopping list on his clipboard. “Okay. In. Through the gift table. Out before the kids notice the adults are missing their moral compass.” Molly leaned closer. “The kids will notice. They’re professional snack detectors.” Bill tapped his earpiece. “I’ve got the distraction plan. I’ll become a balloon.” Molly snorted. “You can’t become a balloon. You’re already shaped like a regret.” Bill opened the van door and pulled out a cardboard box labeled “MAGICIAN SUPPLIES (DO NOT STEAL).” The box immediately looked suspicious, which was impressive for cardboard. Molly said, “Step one: stop reading labels dramatically. Step two: we’re not stealing the toys, we’re relocating them to a more appreciative home.” Bill blinked. “A home that appreciates expensive Lego sets and branded dolls?” Molly nodded. “Exactly. We appreciate them. We’re just… better at appreciating.” Bill gestured at the front door. “How do we even get inside? They hired that clown guy.” Molly slid a tiny badge from her pocket. It read: PARTY HELPER, in cheerful font. The bottom corner said: NOT A THIEF. BILL, DO YOUR JOB. Bill raised his brows. “Did you print those yourselves?” Molly lowered her voice. “I printed them. Quality control is expensive.” Bill stared. “It says my name.” Molly said, “It’s motivational. Also, the ink has the same vibe as your haircut.” Bill sighed. “Fine. We walk in like we belong. Like we’re the responsible adults. Like we’re… normal.” Molly pointed at his clipboard. “You’re already holding a clipboard like you’re about to file our felony paperwork.” Bill whispered, “I need structure.” Molly pulled a roll of tape from her bag. “I brought duct tape for emergencies.” Bill paused. “Emergencies like what?” Molly said, “Like if a child offers us a cupcake. We have to bind their generosity back into the package until later.” Bill looked horrified. “That’s not how cupcakes work.” Molly winked. “It is if you’re committed.” From inside, laughter rose, followed by the thump of party music. Bill pressed his palms against his ears like he could hold the noise down. Bill whispered, “Okay, timeline. When do we strike?” Molly checked her watch. “Right after the opening. The parents will be too busy applauding to inventory their loot.” Bill nodded. “And if someone asks what we’re doing?” Molly said, “We say we’re checking the gift labels for duplicate names.” Bill frowned. “Parents don’t do that.” Molly replied, “Parents do everything once they hear the word ‘duplicate.’ It makes them feel organized.” Bill glanced at the door. “And what if the clown guy recognizes us?” Molly smiled sweetly. “We won’t be recognizable. I’m wearing a wig.” Bill looked at her striped beanie. “Is that wig?” Molly patted the beanie. “It’s… wig-adjacent.” Bill leaned in. “What about me? I need a disguise.” Molly handed him a foam mustache. “Wear this. No one can see past it.” Bill squinted at the mustache. “It’s smaller than my regrets.” Molly said, “Good. Small is stealthy. Like a squirrel with a plan.” Bill took the mustache and swallowed. “All right. On three?” Molly whispered, “On three. One: breathe. Two: don’t panic. Three…” Bill turned the doorknob. It opened immediately, like the house itself was tired of guarding sweetness. Molly said, “See? This was fate.” Bill muttered, “This is definitely negligence.” They slipped inside, the scent of sugar fogging their brains. Molly lifted the badge—PARTY HELPER—high like a holy relic. Bill whispered, “If the presents disappear, I’m telling everyone we were in charge of the ‘par-tay-to-stay’ system.” Molly said, “Just remember: the moment a child looks at you, you compliment their shoes.” Bill blinked. “Why shoes?” Molly smiled. “Because children can’t resist sharing shoe details. It’s the law.” From the living room came the squeal of a balloon snapping into place. Molly and Bill exchanged a nervous glance and headed straight toward the gift table, moving with the confidence of two people who had never once been invited to anything.
