Moonlight spilled over the party supply shop as Molly and Bill whispered, plotting with exaggerated seriousness for a harmless prank. Molly: "Bill, picture the party hats, balloons, and tiny fingers: chaos disguised as cheer, and us grinning at it tonight." Bill: "Molly, we will drift through the glow sticks like smoke, collect the presents without anyone noticing our silhouettes tonight." Molly: "But we must avoid alarms, cameras, and the rumor that the cookies glow in the dark when startled perhaps." Bill: "We’ll time it with the magician’s finale, pretend we’re part of the act, and vanish before the Encore arrives." Molly: "If someone notices, we pivot to autograph mode, sign nothing, and bow gracefully, like confused performers slipping away together." Bill: "Meanwhile, I’ll distract the adults with balloon drop music and a pretend treasure map, all entirely innocent theater tonight." Molly: "If the map points to dolls, we swap them for costumes and chase the mislaid socks to the exit." Bill: "Then we improvise confetti rain and claim it was research for a charity calendar, namely ours for the kids." Molly: "Deal, Bill; we exit with smiles, and nothing cracks, except maybe the ceiling’s celebratory glow that makes us heroes."
