Molly leans against a chipped park bench, crumpling a neon children’s party invite in one fist while Bill jiggles a lopsided fake balloon dog in the other. “Confirm the party’s 3pm start?” “Yep—cake cut at 4, that’s our chaos window.” “Cake swarms mean parents’ eyes glued to icing messes, not the gift table.” “Gift table’s behind the piñata, right? Tinsel-draped?” “Exactly—hard to miss but easy to grab in costumes.” “I brought a neon clown wig—you take the fairy wings I snagged?” “Fairy’s better—kids let fairies hover near presents without squawking.” “What about the dinosaur-suited bouncer?” “I’ll slip him a lollipop spiked with sleep syrup—nods off in five.” “Stolen lollipop?” “Corner store yesterday—perfectly dosed.” “Kid witness plan?” “Tell ’em we’re gift fairies rearranging for Santa’s check.” “Santa angle’s genius—they’ll zip it.” “Stash loot in a giant beach bag under the slide.” “Slide stash—smart.” “Meet at the oak tree post-heist, split by loot value.” “What about the sticky candy-filled presents?” “I take those—you hate sticky.” “Deal.” “Don’t forget your wig—last time you forgot disguise and got chased by a goose.” “I won’t—goose trauma’s still fresh.” “Good—one misstep and we’re stuck explaining to tantrum-throwing six-year-olds why we’re stealing their toy trucks.”
