Molly leaned against the van, tapping a crumpled map of the Hendricks' backyard. "Okay, Bill, listen up. Bounce house is the blind spot. Guards—I mean parents—won't see us coming." Bill snorted, adjusting his ridiculous clown wig. "Guards? Molly, it's a seven-year-old's birthday party, not Fort Knox." "You'd be surprised. Suburban moms are vicious with a Pinterest board and a grudge." "Fine. So what's the plan, oh fearless leader of felonious fun?" "We go in as entertainment. You're the clown, I'm the balloon lady. We work the crowd, distract the kids with magic tricks, and while everyone's watching you fumble a rabbit out of a hat—" "I don't fumble!" "—I sneak into the gift tent and load the presents into the balloon cart." Bill crossed his arms. "That's insane. Also, slightly evil. They're presents for a kid's birthday." Molly shrugged, grinning. "Correction—they're presents for us. Think of it as redistribution of festive wealth." Bill sighed, pulling the wig down tighter. "You know, one day, karma's gonna hit us like a piñata stick." Molly smirked, tossing him a red rubber nose. "Maybe. But today, we're just here for cake and chaos."
