Molly unfolded the crayon-scribbled floor plan across the dashboard, pinning one corner with a half-eaten doughnut. Across the street, balloons bobbed on the mailbox like cheerful security guards. “Bill, we enter through the garden gate,” she said. “The one guarded by a terrier in a bow tie?” “That dog can be bribed.” “With what?” “Ham.” “We don’t have ham.” Molly patted her coat. “I always have emergency ham.” Bill squinted at the house. “Then we cross the lawn, avoid the magician, and grab the presents?” “Correct.” “What if the magician saws me in half?” “Try to look recyclable.” Inside, children shrieked with sugar-powered delight. A clown staggered past the window, pursued by a toddler wielding frosting. Bill swallowed. “This feels wrong.” “It’s a redistribution of wrapping paper.” “It’s a six-year-old’s birthday.” “Fine, we only take the noisy toys.” “That’s somehow worse.” Molly sighed, then spotted a mountain of gifts beside the cake. Atop it sat a card reading: For Charity Toy Drive. Bill grinned. “Steal from a toy drive?” Molly folded the plan. “New plan. We rob the piñata.” “With ham?” “With dignity.” They marched toward the gate as the terrier accepted payment in advance.
