Molly crouched behind the hedge, wearing a unicorn mask and the expression of an accountant confronting glitter. Bill unfolded a map of Mrs. Puddlewick’s garden, which was mostly arrows, cake stains, and one ominous sticker reading Bouncy Castle. "Molly, the presents are stacked by the clown, under the table shaped like a pirate ship." "Perfect. Children fear pirates." "They adore pirates." "Then we weaponize boredom. You discuss municipal parking permits." "That made my dentist cry." "Good. While they nap standing up, I roll the wagon in." "The wagon says Happy Birthday, Timmy." "Camouflage, Bill." "What about the dog?" "Bribe him with sausage." "He's a balloon dog." "Then bribe the clown." "With sausage?" "Never negotiate hungry." A shriek rose as twelve children attacked the piñata with administrative fury. Molly checked her watch; Bill checked his conscience, found it absent, and sneezed confetti. They advanced two steps before Timmy toddled over, solemnly offering them paper crowns. Molly froze. Bill put his on. "Abort?" he whispered. "After cake," Molly said, adjusting her crown. "Then presents?" "We'll steal the thank-you notes." "One cupcake." "And the tiny sandwiches." "Strictly as disguises." "We're monsters, but tidy." "Fine." The clown winked, recognizing professional incompetence when he saw it.
