Molly adjusted her oversized clown wig and grinned at Bill, who was half-dressed as a very suspicious-looking magician. "Okay, genius, we hit the party at peak present time. Right after cake but before the sugar crash." Bill tugged at his fake mustache. "This is insane, Mol. We're stealing from toddlers. What if they cry? I can't handle crying kids. Last time I stole something small it followed me home and told its mother." "They're not toddlers, they're six," Molly said, checking her swag bag. "Big difference. Six-year-olds are vicious. We'll be doing the parents a favor. Less fighting over who gets the plastic truck." "We're gonna get caught," Bill muttered, practicing his balloon animal skills with shaking hands. "Some kid's gonna point at us and yell 'stranger danger' and then it's game over." Molly rolled her eyes. "Not if we stick to the plan. You distract with magic tricks, I swap the presents with the identical empty boxes we wrapped this morning. In and out in six minutes." "Empty boxes? That's just mean." "They're getting the same wrapping paper back. It's basically recycling," she said with a wink. "Think of it as performance art. The Great Present Heist of 2025." Bill sighed. "Fine. But if any kid asks for my autograph, I'm out."
