(They crouch behind a lamppost, plotting with goofy seriousness, pretending they're bank rooks in a candy shop at night now.) Molly: "Bill, the giggling party favors will be our distraction, and the greatest loot is adorably wrapped chaos waiting inside." Bill: "Relax, Molly, it's not theft if we borrow happiness, then return everything with glitter and stories and apologies tonight." Molly: "We plan with lullabies and cupcakes as cover; let the candy confetti rain, and nobody will notice our footprints." Bill: "We won't harm anybody; we simply relocate the nicest gifts to a shelf, then pretend a party magic prank." Molly: "The detective dog gets sleepy when swish-swish balloons pass; we glide past, like sneaky mice in velvet sneakers tonight." Bill: "Meanwhile, the clowns misdirect the crowd with juggling oranges, and we wager on perfect timing, collecting joy, not causes." Molly: "If a parent pouts, we offer a high-five and a badge that says 'Official Snowflake Scout,' crisis diverted instantly." Bill: "We stash the gifts behind the curtain, write a note to Santa, and leave a soft trail of peppermint." Molly: "Then we tiptoe toward the exit, hats tilted, mouths wiped clean of mischief, waving merrily like the party's heroes."
