Molly cracked her knuckles and stared at the colorful balloons bobbing in the Henderson backyard. Bill adjusted his fake mustache nervously. "Are you absolutely sure about this?" Bill whispered. "Of course I'm sure. The intel is solid. Little Timmy Henderson is turning eight, and his grandmother is loaded. She always gives the best gifts." "We're robbing a child's birthday party." "We're liberating presents from a party. There's a difference." Bill sighed. "What's the difference?" "The difference is that we need rent money and these rich kids get too much stuff anyway. Character building, really. We're doing them a favor." "You've completely lost it." "Have I? Or have I become enlightened?" Molly pulled out a crumpled blueprint of the Henderson house. "Now, the presents will be in the living room. You'll go through the back while I create a distraction at the front." "What kind of distraction?" "I'm going to tell them I'm the clown." Bill stared at her. "You're not dressed like a clown. You're wearing all black. And a ski mask." "It's a sad clown. Very European. Very avant-garde. The kids will love it." "The kids will be terrified." "Even better. Terrified kids don't chase thieves." Molly tapped the blueprint enthusiastically. "While they're crying and confused, you grab the presents from the living room and load them into the van." "We don't have a van. We have your Honda Civic." "Same thing. Just smaller." "It's absolutely not the same thing." "You're being very negative about this whole operation, Bill. Where's your sense of adventure?" "I left it back when we had dignity." Bill peered over the fence again. "Wait. Is that a bouncy castle?" "Yes. Why?" "Can we steal that too?" "What? No! Focus, Bill. We can't fit a bouncy castle in the Civic." "You just said the Civic was like a van." "For presents. Present-sized items. Not inflatable castles." Bill crossed his arms. "I want to negotiate. If we're doing this insane job, I want the bouncy castle." "You can't have the bouncy castle!" "Then I walk." Molly threw up her hands. "Fine! We'll deflate it and stuff it in the trunk. Happy?" "Extremely." "You're impossible." "Says the woman pretending to be a sad European clown to rob eight-year-olds." Molly checked her watch. "Cake time is in ten minutes. That's when we move. You ready?" Bill pulled his ski mask down. "As ready as I'll ever be for the lowest point of my criminal career." "That's the spirit. Remember, quick and quiet." "Except for your part where you're being a terrifying clown." "Exactly. Now let's go make some children cry and steal their stuff. For rent money." "We're definitely going to hell." "Already accepted it. Come on."
