M: Hello, Mary, how are you today? I hear you weren't well last week. ,F: I'm much better now. Thank you. ,M: What was the matter? Nothing serious I hope. ,F: Oh, no, I had a bad cold and had to stay in bed for 2 days. ,M: I'm glad you're better. Anyway, I hope it was the last cold of the winter and not the first cold of the summer. What about your friend Dan? I hear she's ill, too. ,F: She was ill, but she's all right now. I think she caught my cold. ,M: Everybody seems to have one now. I expect it's the sudden change of weather, 1 day hot and the next day cold.
