Molly, perched on a rusty fire escape, looked down at the party below. "You sure about this, Bill?" Bill, adjusting his mask, grinned. "We've got a buyer ready, darling. Plus, think of the kids' faces when they wake up to empty presents." Molly chuckled. "You're a monster, you know that?" Bill shrugged. "But a monster with a plan." They slipped over the edge, landing silently on the roof. Molly pulled out a small toolkit. "So, Bill, how do we get past the security?" Bill adjusted his earpiece. "Just go with the flow, Molly. Remember, no one's expecting us." Molly sighed. "And what if security doesn't just 'flow' with us?" Bill smirked. "Then we'll just 'flow' with them." Molly rolled her eyes but cracked a smile. "Let's do this." They moved silently through the party, stealing presents as the children sang and laughed. A group of kids gathered around the Christmas tree, their laughter echoing through the room. Bill leaned in, whispering to Molly, "Now remember, we're just here to collect presents, nothing more." Molly nodded, her eyes sparkling with mischief. "Right, just presents, just presents."
