F: Hello, who's that? ,M: Hello, Mrs Black. I'm David. I'm coming to fix your TV set. ,F: Oh, come in please. ,M: But where is the TV? In the living room? ,F: No, not this one. This way please. It is laid in the bedroom. The old one which we bought when we got married. ,M: Oh, let me turn it on. Yes, it's really a little old, the scene is not clear. Why not change it? ,F: Well, it can mark the old days so I'd like to keep it. Can you help me make it better? ,M: Sure, I'll try my best. Perhaps it needs a new kinescope. Please wait for a moment. ,F: Aha, a miracle happened. Thank you so much, Mister David. ,M: It's my pleasure.
