Model response

Molly crouched behind the hedge, peering at the backyard circus of balloons, cupcakes, and sugared chaos. Bill unfolded a map drawn on a napkin, upside down. “Phase one: we enter through the bouncy castle,” Molly said. “That’s not a door,” Bill whispered. “It’s a lifestyle choice.” Bill squinted. “And phase two?” “We blend in.” “You’re wearing a black turtleneck.” “So are eight of the dads.” A child shrieked with joy as a magician produced a rabbit from a hat. Bill flinched. “The rabbit saw me,” he said. “The rabbit knows nothing.” Near the picnic table, a mountain of wrapped gifts glittered beneath a banner reading HAPPY BIRTHDAY, SOPHIE! “Remember,” Molly murmured, “we’re not stealing. We’re relocating.” “To our van.” “Temporarily forever.” Bill adjusted his fake mustache, which was made of licorice. “What if someone asks who we are?” “Say you’re the balloon inspector.” “That’s not real.” “Neither is your mustache.” A gust of wind lifted the napkin map into the goat petting area. The goat ate phase three. Bill sighed. “Abort?” Molly watched Sophie hand a cupcake to a crying toddler. She groaned. “Fine. New plan.” “We leave?” “We buy her a better present. Then steal the magician’s rabbit.” The rabbit stared. Bill swallowed. “He heard you.”
