David NichollsYou know what i can't understand? You have all these people telling you all the time how great you are, smart and funny and talented and all that, i mean endlessly, i've been telling you for years. So why don't you believe it? why do you think people say that stuff, Em? Do you think it's a conspiracy, people secretly ganging up to be nice about you?
