Molly crouched by the hedge, hearing party squeals. “Bill, slow. Balloon chaos equals arrest.” Bill nudged a grin aside. “I’m slow. I’m stealthy. I’m basically furniture.” A frosting truck rumbled past. Molly pointed at the open garage. “We swipe all presents, not the snacks.” Bill glanced at the clown’s horn. “Kids notice snacks.” “They notice ponies more,” Molly said. “So we distract them with kindness.” Bill raised a brow. “My kindness is… questionable.” “Then my kindness will cover your kindness,” Molly replied. “Swap hats, wave at the parents, and act like you forgot the napkins.” Inside, a birthday song thumped. Bill breathed. “What’s the plan if someone talks to us?” Molly slid a bag from her pocket. “We compliment their decorating. Then we vanish.” Bill whispered, “And if they hug us?” “We survive hugs,” Molly said. “After all, we’re professionals.” Bill checked the lock with a click. “Ready for the great present rescue?” Molly smiled. “Rescue implies we’re heroes. Theft implies we’re legends.” They slipped through the side door as laughter surged. Bill steadied the bag, and Molly checked the guest list on the flyer. The stage lights blinked like impatient fireflies. Somewhere, a child shouted “Look!” and the adults laughed, turning their backs for one blessed second at once.
