Deep in the bushes near the brightly decorated backyard, Molly and Bill crouched low to avoid detection by any wandering party guests or nosy neighbors. The air was filled with the sound of bubbling laughter and the scent of freshly baked cake and candy. Colorful wrapping paper could be seen through the fence. "How do we get the presents out without being seen?" Molly whispered cautiously to her companion. Bill peeked over the leaves with an eager expression on his face. "Simple. We pretend to be the pony ride guys. While the kids are riding, we load up the van with all the gifts." "This is crazy. They're just kids," Molly said, her voice filled with doubt and hesitation. "Kids with very expensive toys. We'll be doing this quick and quiet. In, swap the presents with empty boxes, out. No one gets hurt," Bill explained enthusiastically despite her concerns. Molly paused for a long moment, considering the options carefully and weighing the risks involved in their latest scheme. "Fine. But we leave the big teddy bear. It looks too much like you." Bill chuckled at the comment and gave her a playful nudge. "Deal. Let's get our fake mustaches on and crash this party."
