Molly and Bill crouched behind a hedge outside the brightly decorated community hall, where a banner announced Tommy’s seventh birthday and promised MAGIC, GAMES, AND SURPRISES! Unfortunately, the surprises were currently stacked beside the entrance: wrapped boxes, gift bags, and one enormous parcel shaped suspiciously like a washing machine. Molly checked their equipment: two black masks, a grappling hook, three cupcakes, and Bill’s alarming collection of disguises. “Remember: smiles, balloons, and absolutely no tripping over the cake,” Molly whispered. Bill adjusted a purple party hat over his ski mask. “I never trip. I perform unexpected horizontal entrances with dignity.” he replied, immediately snagging his boot on a lawn flamingo. The flamingo toppled noisily, triggering a motion-sensitive recording that announced the birthday. Bill froze mid-wobble. Inside, children cheered, mistaking the crash for entertainment. Molly seized the opportunity, marching through the door with a tray of cupcakes held like royal offerings. Parents waved her onward. Bill followed, attempting what he called stealth but what everyone else recognized as interpretive dancing. They reached every present. Molly stuffed boxes into a laundry cart, while Bill distracted the children by demonstrating a spectacular balloon animal. Unfortunately, he made a giraffe that resembled their getaway driver.
