The room smelled of vanilla frosting and balloons as Molly and Bill crouched behind a row of velvet chairs, grinning at the chaos beyond. They treated the plan as theater, a caper where kindness outshines cleverness and mischief wears a party hat. The children's party next door hummed with sugar and laughter, a stage where they rehearsed their parts, not their methods. They spoke in whispers and gestures, mapping a fantasy route through the periphery of cupcakes and piƱatas. Every thought was wrapped in whimsy: costumes that sparkled, a confetti escort, giggles as their 'escape'. They reminded themselves the point was misdirection, not harm, a harmless prank that left the presents sparkling and the kids grinning. When doubt flickered, Molly braided a joke into the air; Bill tucked a feather boa around his neck. The moment felt ridiculous and perfect, a silly misdeed dressed as a surprise. They squared shoulders, rehearsed lines one last time, and stepped toward the party's glow, hearts rising with music. In their minds, the plan shone bright, silly, and completely harmless tonight. Laughter trailed behind. "We'll stage a giggly caper." "Then we mingle with the partygoers." "No real theft, just mischief." "A harmless legend, okay?"
