Bill crouched beside the hedges like a malfunctioning scarecrow, his face pressed into the shrubbery in a way that suggested he was trying to grow eyebrows. Across the street, a cheerful house glowed with multicolored string lights, and somewhere inside, a recorded voice yelled, “FIVE MINUTES UNTIL FUN!” as if time itself had joined a clown union. Molly adjusted her beanie, which read BIRTHDAY HERO in glitter letters that made her look like a morally flexible toothpaste commercial. She held a tiny clipboard the size of a postcard, because nothing said “professional” like pretending to be a substitute teacher. Bill whispered, “Do you think the dad will notice if the presents… go missing?” Molly whispered back, “Depends. Is he the type of parent who opens a fridge and forgets what he was doing? If yes, we’re invisible.” Bill’s eyes widened. “He once complimented the toaster.” Molly nodded. “Then we can absolutely steal his child’s joy. Respectfully.” Bill blinked. “Respectfully?” “Like stealing a cookie from a cookie jar,” Molly said. “You don’t kick the jar down. You just… redirect reality.” Bill glanced at the front door. “Okay, but there are balloons. And a clown.” “Balloons are just suspended optimism,” Molly said. “Clowns are just people with commitment issues and face paint. Both can’t stop us.” Bill reached into his jacket and pulled out a bag of something crinkly. He held it up like a magician unveiling a rabbit. Molly peered. “Are those… training socks?” Bill shrugged. “They’re grip-enhancing. For stealth.” Molly stared at him. “Bill, stealth socks will not make you stealth.” “They might make me sock-stealth.” Molly pinched the bridge of her nose. “We’re not sock-stealthing anything. We’re present-stealthing. There’s a difference.” Bill grinned, relieved to have a mission with a proper label. “Right. Present-stealth.” Inside the house, the party thumped with bass from a playlist titled KIDS’ GREATEST HITS. A squeal of laughter erupted, followed by the sound of someone clapping too loudly, like they were trying to summon applause from the ceiling. Molly leaned closer to Bill, her voice turning solemn in the way only thieves can manage. “Plan A: we take the presents. Plan B: we take the presents faster so we feel less guilty.” Bill swallowed theatrically. “Guilt isn’t in our inventory.” “It is,” Molly said. “It’s in the fine print. It’s just… seasonal.” Bill looked down at his clipboard. “What does your clipboard say?” Molly flipped it open. It contained exactly three bullet points and no handwriting, only doodles of stick figures wearing tiny masks. Bill squinted. “So it’s more of a… mood board.” “It’s a blueprint for vibes,” Molly said. “Listen. When the kids are busy with games, their attention becomes a distracted flock of birds. We become the hawk that steals toys.” Bill pointed at his own chest. “I’m the hawk?” “You’re the hawk with the questionable headwear,” Molly said, eyeing the balloon bobble that was tied to his hair. It bobbed slightly, betraying him with every micro-movement. Bill tugged at it. “It’s my good luck balloon.” “It screams ‘please talk to me,’” Molly muttered. Bill frowned. “If someone asks, we’ll say we’re balloon technicians.” Molly sighed. “Bill, you are not a balloon technician.” “I can troubleshoot,” Bill insisted. “I once fixed a party favor by… removing it from the carpet.” Molly leaned back, considering. “Okay. Balloon technician if questioned. But you cannot talk. Balloon technicians talk in short, mysterious phrases.” Bill nodded, serious. “Like… ‘Balloons respond to calm.’” Molly blinked. “That sounded like therapy.” Bill brightened. “Therapy is mysterious!” The party door opened a crack, letting out a gust of warm, sugary air and the faint smell of frosting. A stream of parents’ voices floated outside, discussing cake flavors with the intensity of war councils. Molly checked her watch. “Moment is near.” Bill’s grin returned, sharp and eager. “All right. We swoop. We grab. We escape into the night like two—” “Two professional criminals?” Molly offered. “Two birthday burglars,” Bill finished. Molly clapped her hands once, quietly. “There we go. Birthday burglars with manners. Remember: we only take presents. Not snacks. The snacks are bait, and I refuse to be distracted by bait.” Bill whispered, “What if there are snacks in the presents?” Molly smiled thinly. “Then the presents will have to live a little longer.” They crept toward the front steps, their shadows wobbling across the porch like nervous toddlers learning to dance. Inside, the voice announced, “Now opening the gift bags!” and Molly and Bill exchanged a look that said, in perfect thief-speak: let’s ruin a party—tastefully.
