Do you think you can help me out? ,M: Sure, what's this project about? ,F: Well, I should interview someone that I admire about their jobs. ,M: Well, I am an expert when it comes to my job. Accounting is a respectable job and one that I am always happy to talk about. ,F: Dad, I know how much you love your job. It isn't that I don't admire you.
