AI
Molly crouched behind the hedge and lowered her binoculars. "Okay, Bill. Target is a seven-year-old named Trevor. Forty-two guests. One bouncy castle." "Why does the bouncy castle matter?" "Because it's chaos, Bill. Nobody will notice us." "I notice it. It's shaped like a dragon." "Focus. The presents are on the patio table. You'll be dressed as the clown." "I refuse to be the clown." "The real clown is booked for two o'clock. It's five to. Nobody has met him. Children trust strangers in oversized shoes." "That's horrifying, and also useful." "Thank you. I'll be the pizza lady. While you distract the parents with balloon animals, I swap the gifts for identical boxes full of cardboard." "I can't make balloon animals." "Everybody can make a balloon dog." "Molly, I once made a balloon tragedy. A child cried." "Then make a tragedy again. Parents love a distraction." "What if Trevor recognizes me?" "He's seven. He can't recognize his own shoes." "And if the real clown shows up?" "Then we improvise. Everyone loves two clowns." "Nobody loves two clowns." "Put on the nose, Bill."
