M: My history professor says I should think about a job in politics, but I don't think I'd make a good politician. ,F: Why not? ,M: You know me. I'm not good at dealing with people and politicians have to work with people all the time. ,F: That's true. So what do you think you want to do? ,M: I think I will be a good artist. I love painting pictures. ,F: That reminds me of a problem I'm having. You know my parents have a restaurant, right? They want me to be the manager. ,M: And you want to? ,F: No way. A restaurant manager has to manage other people. It would be terrible. I'm too disorganized. Honestly, I want to be a teacher because I like working with kids and I'm good at it.
(A) M: That's true, I remember you are really good at working with kids. (B) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that?
