I'd read to you. ,M: Alright, go ahead. ,F: Question one says, "Do you think of yourself as lazy or hard working?" I can probably answer that for you. ,M: OK, I know I am lazy. I don't like to work too hard, especially around the house. ,F: You're right about that. Next question, are you more frequently patient or impatient? ,M: Umm, I'd say, I'm patient, especially when I have to wait for you. ,F: That's true. I guess I don't have to ask the next question.
