What’s wrong with the woman?

M: Oh, it’s you, Mrs. Green. Come in and sit down. Now, what was it? Oh, yes, your cold. Do you feel any better?
W: Well, no, I’m afraid not, doctor. I feel drowsy and my throat is still sore.
M: Let me take your temperature... Hmm, you still have a high temperature. Have you been resting, as I told you the day before yesterday?
W: It’ s so difficult to have a rest, doctor, you know, with a house to run on and six children to look after.
M: Well, I’ ve given you my advice. I’ m sorry, but rest is necessary for your recovery, otherwise I wouldn’ t have insisted on it. You must rest as much as possible, or your cold might get severer, do you understand?
W: Yes, I understand. I’ 11 try to do as you say.
M: Very well then. I’ 11 repeat that prescription for tablets, but the only effective treatment is rest. Ask the next patient to come in please.
