Mary: Mark. I don''t want to listen to any more of your rubbish. I had enough of you. Don''t try to call me again. I''ll pull out the wire.
Lucy: Hello, Mary. It''s me, Lucy. Don''t hang up.
Mary: Oh, is that you, Lucy? Where did you spring out? I thought you were in Canada.
Lucy: I returned yesterday. The first thing I wanted to do after I went back was to get in contact with my old friends. I had been trying to get you on the phone all morning, but your line kept busy. Just now, when I finally got through to you when the phone went dead on me. Did you slam it down? What''s going on between you and Mark? A War?
Mary: More than a war. A divorce.
Lucy: You are joking, aren''t you? You used to love each other so much.
Mary: It''s all over now. I don''t want to talk about it any more on the phone.
