I found your comment: "But the money comment is all part of who he is. He loves money: counting it, trading it, scheming about it. He's not worried about money, but he is fascinated by it. He spent more time coming up with the pricing scheme for his lemonade stand than actually operating it." pretty funny. Sounds like you've got a budding entrepreneur on your hands. Next thing you know he's going to start hiring operators for the stand and coming up with pricing strategies to segment the demand curve for cold drinks served by cute kids. (think: organic lemonade for only 2X the price!)
