Molly flattened herself behind the bakery van and peered at the pastel house. “You’re sure this is the one?” Bill adjusted his cap and sniffed. “The one with the inflatable giraffe, the brass band of children, and enough loot to make Santa file for bankruptcy? Yes.” “Presents are stacked by the hallway,” Molly whispered. “I saw them through the window. Ribbon mountain. Card avalanche.” Bill grinned. “Beautiful. We go in as balloon delivery.” “We don’t have balloons.” “We have confidence.” “That’s not a balloon.” “It’s cheaper.” Inside, the party shrieked with sugar-fueled joy, while parents chatted near the cake table and one clown twisted a dog into a regrettable swan. Molly and Bill slipped through the side gate with a borrowed trolley and two solemn faces. Bill said, “If anyone asks, we’re from the generosity department.” Molly whispered, “That sounds fake.” “Everything we do sounds fake.” They reached the pile of presents, glittering under a paper lantern. Molly lifted the first box. “Heavy.” “Excellent,” said Bill. “That means love.” “Or batteries.” “Even better. Batteries are hope, but practical.”
