Molly adjusted her oversized sunglasses and leaned across the wobbly diner booth. “Okay, Bill, listen. We hit the party at exactly three-fifteen, right when they’re singing Happy Birthday. Nobody’s watching the gift table during that off-key massacre.” Bill slurped his coffee and grinned like a man who’d already spent the loot. “You’re a genius, Mol. Pure evil wrapped in sparkly logic. But how do we blend in? We look like we rob banks for a living.” “We look like we rob banks because we do rob banks, you walnut. That’s why I bought the props.” Molly slid a plastic bag across the table. “You’re going as the world’s saddest clown. I’m the balloon artist. Kids won’t suspect a thing.” Bill peeked inside and recoiled. “A clown? With the red nose and everything? I’ll have nightmares about myself.” “Better than the alternative. Last time you tried blending in you wore that fake mustache and the birthday mom thought you were her ex-husband. We barely escaped with the cake.” “Fair point,” Bill muttered. “Fine, clown it is. What’s the exit strategy? Those ankle-biters are fast when sugar’s involved.” Molly tapped a crude map drawn on a napkin. “Back door by the bounce house. I deflate it while you load the presents into the fake ambulance we’re borrowing. Parents see a clown and a paramedic carrying boxes, they assume it’s part of the show. We’re basically performance artists with larceny credentials.” Bill chuckled. “You’re enjoying this way too much. We’re stealing teddy bears and junior chemistry sets, not diamonds.” “Sentimental value, Bill. Those presents are worth their weight in parental guilt. Plus little Timmy’s getting a PlayStation 5. I saw the box. We can flip that in twenty minutes flat.” “Timmy’s gonna cry,” Bill said, almost sounding sorry. “Timmy cries when the juice box is warm. He’ll survive. We’ll leave him a balloon animal as restitution. Maybe a sad little giraffe to match his emotional state.” Bill leaned back, arms crossed. “You’ve thought of everything except the dog. There’s always a dog at these things, Mol. Some yappy little monster that sniffs out guilt like it’s bacon.” Molly waved a dismissive hand. “I’ve got bacon-flavored tranquilizer treats. Non-harmful, just makes him dopey and friendly. He’ll think we’re his new best friends.” “You’re terrifying when you’re organized.” “Thank you. Now, important question: do we take the piñata too? There’s candy in there and I’ve got a sweet tooth.” Bill stared at her. “We’re not animals, Molly. The piñata stays. We have standards.” “Since when?” “Since never, but I’m drawing the line at destroying a paper donkey in front of thirty screaming children. My conscience has limits.” Molly sighed theatrically. “Fine. Piñata lives. But the presents are ours. We hit hard, we hit fast, and we leave with enough loot to finally buy that taco truck we’ve been talking about.” Bill raised his coffee mug in a toast. “To robbing children and achieving our dreams.” Molly clinked her mug against his. “And to never speaking of this job again after today.” “Deal,” Bill said, already laughing. “Let’s go make some memories they’ll need therapy for.”
