W: So, you’ 11 be getting dressed up later—before you go to the BBC television studios.
M: Yes, but to tell you the truth, Mary, I prefer working in radio.
W: You prefer radio?
M: That’ s right. You can dress down in a radio studio.
W: What do you mean?
M: You can dress down. You can wear something casual. There’s no need to get dressed up.
W: Well, I always try to make an effort to look smart!
M: Yes, of course, you always look fantastic, Mary. But you don’t have to dress up for radio. The audience can’t see you.
W: Ah, I see what you mean. In TV the audience can see you, so you have to look your best.
M: Exactly. You have to dress up. You have to put on something smart so you look the part.
W: Yes. I suppose if you’ re on TV, you have to look like a TV presenter: you have to be dressed right.
M: But in radio, the listeners can’t see you so we can dress down if we want to.
W: Yes. That’ s why I sometimes wear jeans to work.
M: Exactly, on radio. I can take off my tie! I can even take off my shoes!
W: I don’t think so! You don’t have to wear your tie—you can take that off if you want to, but please don’t take off your shoes!
