Where does the conversation probably take place?

W: Shall I phone and tell your secretary you’re not coming today?
M: Yes, please, dear. Tell her I’ve got a cold and have a headache, but hope to be back in a day or two. You’d better say I’m staying in bed.
W: But you are not in bed. Do you want me to tell a lie?
M: Oh, it’s only a little one, dear. I’m not making a false excuse. I really have a bad headache.
W: Then put the cigarette out. It’s very foolish of you to smoke when you’ve got a cold.
M: Very well, dear. You’re quite right.
W: You never listen to me.
M: Don’t I?
W: Look, There’s some boiling water in the kitchen. Here you are. Do as I tell you now. I’ve put something in the water. That’ll do you a lot of good. Wrap this cloth around your neck and put your nose over the water. That’s right. Breathe in deeply.
M: It smells nice.
W: Now, another deep breath. Now breathe out. Slowly!  Now, breathe in again. Go on doing that for five minutes. I will go and make that phone call to the office.
