Bill slumped into the creaky booth at the back of the dingy diner, his trench coat smelling faintly of cheap cologne and regret. Across from him, Molly nursed a lukewarm coffee, her eyes sparkling with that manic gleam she got before a job. The neon sign outside buzzed like a swarm of angry bees, casting flickering shadows over their map of the upscale suburb. "Alright, Molly, spill it," Bill said, unwrapping a greasy burger. "Why the hell are we hitting a kiddie birthday bash? Last time we went for gold bars, not goddamn piñatas." Molly leaned in, her voice a conspiratorial whisper that somehow carried over the sizzle of the grill. "Think about it, Bill. Rich parents, spoiled brats turning five or whatever. The place'll be crawling with presents—unwrapped, shiny, easy to grab. No alarms on toy trains, right? We swoop in, load up a van full of Lego sets and Barbie dreams, fence 'em for quick cash. It's genius!" Bill snorted, ketchup dripping from his chin. "Genius? It's a clown show waiting to happen. Kids screaming, balloons popping like gunfire. How do we even get inside without some soccer mom calling the cops on our 'suspicious adult behavior'?" She grinned, tapping the map with a chipped nail. "Disguises, dummy. We go as party entertainment. I'll be the face painter—slap on some warpaint as a butterfly, and boom, I'm invisible. You... you can be the magician. Pull rabbits out of hats, distract the rugrats while I stuff the goodie bags into my purse." "A magician? Me?" Bill barked a laugh, nearly choking on his fry. "I can't even pull off sleight of hand without dropping the deck. Remember that casino gig? I fumbled the chips into the dealer's lap. We'd be busted before the cake's cut." Molly waved him off, her excitement bubbling. "Details, Bill! We'll practice. You wave a wand, say 'abracadabra,' and presto—presents vanish into thin air. Or our duffel bags. The kids'll think it's part of the show. 'Hey, where'd my remote-control dinosaur go?' Hilarious!" He rubbed his stubbled jaw, eyeing her skeptically. "And the parents? Those helicopter types with iPhones glued to their hands? One wrong twitch, and we're viral villains on TikTok." "Relax," she cooed, sketching a quick floor plan on a napkin. "We time it for the cake smash—chaos central. I create a diversion: fake a piñata explosion with confetti bombs. You grab the haul from the gift table. In and out in ten minutes. Vans parked out back, disguised as the catering service. Easy peasy, lemon squeezy." Bill paused, burger halfway to his mouth, a slow grin creeping across his face. "You know, Mol, this might actually work. Beats robbing banks with laser grids. Though if a kid bites me, I'm out." She clinked her mug against his soda. "Deal. To the great present heist of '23—may the force be with our loot!" As they huddled over the napkin, laughter echoing in the empty diner, Bill couldn't shake the feeling this caper would be their funniest flop yet. Or jackpot. With Molly, it was always a toss-up.
