# The Birthday Job "We're robbing a six-year-old's birthday party," Molly said flatly. "Best heist ever," Bill replied. "Those kids won't see it coming." "Because it's insane. We're professional thieves, Bill. We've stolen from museums." "Exactly. We've never hit a Chuck E. Cheese's during peak hours." "There's a reason for that." "The presents are stacked by the entrance. In and out, ten minutes max." "Ten minutes? That's how long it takes to cut through one gift wrap." "You're overthinking this. We grab the bags, we leave." "What about security cameras?" "Please. The only security is a teenager making minimum wage." "And the birthday parents?" "Distracted by screaming children. Trust me, they won't notice us." "This is the dumbest plan you've ever pitched, and I watched you try to steal a inflatable pool last Tuesday." "That pool had sentimental value." "It wasn't even yours, Bill." "Exactly. Which means we should definitely steal wrapped presents from kindergarteners instead." Molly stared at him. "So that's a yes?" Bill grinned. "I'm retiring." "After this one job?" "I'm retiring right now."
