听力原文：W: It is so nice here, so restful. I have never been here before. M: No? W: I think I shall come and sit here sometimes. M: Yes? W: Do you lock the hut when you're not here? M: Yes, your Ladyship. W: Do you think I could have a key too, so that I could sit here sometimes? Are there two keys? M: Not as far as I know, there's none. W: Couldn't we get another key? M: Another ! W: Yes, a duplicate. M: It happens Sir Clifford would know. W: Yes! He might have another. Otherwise we could have one made from the one you have. It would only take a day or so, I suppose. You could spare your key for so long. M: I cannot tell you, your Ladyship! And I know nobody who makes keys round here. W: Very well! I'll see to it. M: All right, your Ladyship. W: Good afternoon ! M: Afternoon, my Lady ! What is the exact relationship most likely between the two speakers?
