Molly checked the table. "Okay, party is in five minutes. We need the presents." Bill adjusted his mask. "I brought the loot bags. Do you trust the clown?" "He's a lookout, not a partner." "Fine. I’ll distract the kids with the magic show." "You mean the disappearing socks?" "Mystery is my specialty." Molly pointed. "When they’re distracted, you roll in on the scooter and grab the table." "The tiny scooter?" Bill squeaked. "I have thighs." "Be a gift bag. Nobody suspects a gift bag." "Okay, but what about the loud parents?" "Parents are easier. Compliment the cupcakes and walk." "I’m not charming." "Then pretend you are." Bill squinted. "If we do this, we have to split them evenly." "Twenty gifts, each gets ten." "What about the bicycle?" "You take it. I’ll take the dollhouse." "Deal." "One last thing." Molly narrowed her eyes. "No crying on the bouncy castle." "That was one time!" Bill hissed. "The castle had feelings." "Remember, the piñata is stuffed with candy, not secrets, but I have seen suspicious piñata behavior before. It needs watching. Always watching." "Steal quiet." "Bring balloons. They hide the crowbar. Also, the magician needs a real assistant. We’ll need a wagon." "Steal quiet."
