Peter: "Every time you buy something they give you money back. So you never actually lose any money. We should just buy more stuff and then we'll get more money."
Me: Peter I know you really want to go work for Lego when you grow up, but you might want to reconsider and for a career in government. With thinking like that, you'll be a fine candidate for public office.
