Moonlight pooled on the porch like spilled milk. Bill and Molly hovered near the door, both wearing hoodies that screamed “stealth,” mostly because they were inside-out. “Bill,” Molly whispered, “if a kid sees us, we’re not thieves. We’re… birthday troubleshooting.” Bill’s eyes darted to the window. “Troubleshooting what? Their gift inventory?” “Exactly,” Molly said. “We’re the Gift Whisperers.” Bill snorted. “I whisper ‘mine’ very professionally.” Molly adjusted a tiny grappling hook. “Okay. We go in, grab all the presents, and swap in one ethically guilt-flavored alternative.” Bill blinked. “Like what?” “A used birthday card,” Molly said. “With a message that says, ‘Sorry! Please enjoy our celebration anyway!’” Bill nodded solemnly. “A crime smoothie. Delicious, but illegal.” The porch light blinked on and off, as if the house itself was nervous. “You hear that?” Bill asked. “Kids,” Molly replied. “They’re doing the thing where they pretend not to be excited, and then immediately scream.” Bill leaned in. “So… normal humans.” Molly pulled out a slim card. “Door lock is probably fancy. Fancy locks fear confidence.” Bill raised his eyebrows. “And do fancy locks fear toddler knees?” “Mine do,” Molly said. “Now shh. I’m conducting a symphony of harmless entry.” The lock clicked. Bill exhaled. “That was the smoothest crime-adjacent action I’ve ever witnessed.” Molly pushed the door a crack. “Inside, remember: you’re a dad on his way to return balloons.” Bill whispered, “I’m not a dad.” “Then you’re a very helpful uncle,” Molly corrected. “And I’m the aunt who ‘accidentally’ brought extra glitter.” Bill’s grin widened. “You’re going to get us arrested for being fun.” “We’re already criminals,” Molly said. “Let’s at least be creative.” They slipped through the hall. A banner dangled above them: HAPPY PARTY, as if the house was proud of its own chaos. Bill pointed toward the living room. “There. Treasure.” Molly followed his gaze. The presents were stacked under the tree like brightly wrapped little promises. “Count them,” Bill whispered. Molly crouched and squinted. “Seven large. Nine medium. A suspiciously loud one.” Bill’s voice dropped further. “The loud one’s probably a toy with batteries. Those are the boss-level presents.” “Exactly,” Molly said. “We take the boss-level first. No negotiation with squeaky chaos.” Bill reached for a tape roll. “We just grab and go?” Molly shook her head. “We steal them carefully. Kids notice when paper is torn. Parents notice when paper is missing.” Bill looked at the tree skirt. “So we leave no evidence?” “Evidence is for museums,” Molly replied. “We leave… mystery.” Bill held up a small bag. “What’s in that bag?” Molly smiled. “Non-traceable decoys.” Bill peered in. “Confetti?” “Confetti,” Molly confirmed. “If anyone asks, it’s from the craft table. If anyone doesn’t ask, it’s still from the craft table.” A child’s laugh burst from the backyard. “If they come inside,” Bill said, “we need a cover story.” Molly didn’t look away from the presents. “We’re lost. We’re looking for the cake that ‘should’ve been here by now.’” Bill nodded. “And if they ask who we are?” Molly’s grin turned sharper. “We’re the cake committee.” Bill whispered, “That’s not a real job.” “Neither is theft,” Molly said. “Yet here we are.” She slid her fingers under wrapping paper. “Three, two—” Bill cut in, “Wait. What if one present is actually for the dog?” Molly froze, then laughed quietly. “Then we steal it too. The dog can’t read gratitude.” Bill gathered a medium box. “Okay. I’m on duty. Molly, if anyone screams, I’ll scream back professionally.” Molly hissed, “Professional screaming? That’s your plan?” “It’s in my skill set,” Bill said, already stacking gifts into a tote like he was building a very festive wall. The first balloon animal squeaked from somewhere near the ceiling, as if it had detected intent. Molly glanced upward. “See?” Molly whispered. “Even the balloons are nervous.” Bill dashed a wrapped doll into the tote. “Good. Let the party feel threatened.” Molly snatched the loud, battery-powered box. “All presents accounted for.” Bill leaned toward the hallway. “Almost time to escape?” “Almost,” Molly said. “And when we leave, we leave a single card.” Bill swallowed. “The guilt-flavored one.” Molly nodded. “Sincere. Tidy. Like we’re sorry we stole Christmas’s smaller, louder cousin.” Together, they crept toward the door, tote bouncing with stolen cheer—while somewhere in the house, a voice called, “Where’s the unicorn pinata stuff?!”
