M: Excuse me madam.
W: Yes?
M: I wonder whether you’d help us. We’re doing a survey on smokers’ habits.
W: Well... I’m in a bit of a hurry actually.
M: It’ll only take a few minutes. We’d very much appreciate your help.
W: Well, all right. I can spare that, I suppose.
M: Thank you. Are you a smoker?
W: Yes, I’m afraid I am. My husband is, too. As you can see... I’ve just bought this week’s ration.
M: Would you describe yourself as being a heavy smoker?
W: Heavy... no. [6] I wouldn’t call three packets of twenty a week heavy smoking. No... a light smoker. My husband... he’s different...
M: Yes?
W: I get in twice as many a week for him.
M: You wouldn’t describe him as a chain-smoker...?
W: No... he’s not as bad as that.
M: Right... Thank you, Mrs....?
W: Bradley. Doris Bradley.
M: ... Mrs. Bradley. You and your husband smoke cigarettes I see. What about cigars... a pipe... Does your husband...?
W: Oh he’s never smoked a pipe. He’s the restless, nervy type. [7] I always associate pipe-smoking with people of another kind... the calm contented type...
M: Right. Now let’s keep to you, Mrs. Bradley. When did you begin to smoke?
W: I’m thirty-two now... so I must have been seventeen when I had my first cigarette.
M: I see. Now... Might I ask if you have ever tried to give up smoking?
W: Yes, twice. [8] The first time about six months before getting married. Oh that was because I was saving up and... yes... I used to smoke more in those days. Sometimes thirty a day. So I decided to give it up—but only succeeded I’m afraid in cutting it down.
M: And the second time?
W: Oh the second time I did manage to give up completely for a while. The doctor advised me not to smoke at all. I went for about seven or eight months without a single cigarette.
M: Then you took it up again.
W: [9] Yes... a couple of weeks after the baby was born. It was all right then because the baby was being bottle-fed anyway.
M: Now, Mrs. Bradley. When do you smoke most?
W: Erm, when I’m sitting watching TV or reading a book, but especially when I’m in company. I never smoke when I’m doing the housework.
M: Do you ever smoke at meal times?
W: I always have one cigarette after a meal. [10] Never on an empty stomach. Which reminds me—I must be going. My husband will be waiting for his lunch. And Keith... he’s my son.
M: OK, thank you, Mrs. Bradley.
W: You are welcome.
