VICKI:So, Callum, you'll be getting dressed up later - before you go to the BBC television studios.
CALLUM:Ye... but to tell you the truth, Vicki... I prefer working in radio.
VICKI:You prefer radio?
CALLUM:That's right. You can dress down in a radio studio.
VICKI:What do you mean?
CALLUM:You can dress down. You can wear something casual. There's no need to get dressed up.
VICKI:Well, I always try to make an effort to look smart, Callum!!
CALLUM:Yes of course, … you always look fantastic, Vicki. But you don't have to dress up for radio. The audience can't see you!
VICKI:Ah I see what you mean. In TV the audience can see you, so you have to look your best.
CALLUM:Exactly. You have to dress up. You put on something smart...so you look the part.
VICKI:Yes I suppose if you're on TV, you have to look like a TV presenter should, you have to be dressed right.
CALLUM: But in radio, the listeners can't see you... so we can dress down if we want to.
VICKI:Yes I suppose even I sometimes wear jeans sometimes to work.
CALLUM:Exactly. On radio, I can take off my tie! I can even take off my shoes!
VICKI:I don't think so, Callum! 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!!
Dress down: to wear clothes that are more informal than those you usually wear, for example in an office (与平时比较)穿着随便
Take off: 脱下;移去
