When did the woman give up smoking?

M: Cigarette?
W: No, thank you. I’ve given up, you know.
M: Oh.
W: It’s ten days ago. Haven’t had one.
M: Well, you don’t mind if I had one.
W: Well, all right, then... Oh my goodness! That’s a terrible cough.
M: No, no, it’s not. It’s only... I only get it first thing in the morning.
W: That’s going to make you very unfit, you know.
M: No, it’s all right. It goes in a minute.
W: Why don’t you try and give up?
M: Oh, no. I ought to, but I can’t. It relaxes me, smoking.
W: Really?
M: It does.
W: Well, have you ever thought of just cutting down?
M: Oh, no, that’s all vey well but?.. I wouldn’t enjoy it. I depend a bit on my smoking. I must say.
W: You should do it gradually. I mean... well, if you tried... have you thought of just giving up one day?
M: Yes, oh well, yes, that is quite a good idea.
W: It is.
M: But I think I’d lose count or something.
W: Oh dear! Well, it might be an idea if you started eating sweets.
M: Oh no, I couldn’t do that. I couldn’t possibly...
W: Why?
M : Well, it makes you fat.
W: Well, do you think that matters? Don’t you think it is better to be fat than to be unhealthy?
M: No, I don’t. I’ d rather be fat... Well, I’ d rather be thin than fat, certainly.
W: Oh dear. Well. Hey! I’ve got a good idea!
M: What’s that?
W: Why don’t you go to a hypnotist? My sister did!
M: Oh, look, you don’t seem to realize that I like smoking. If I gave it up, if I didn’t smoke at all, I’d probably end up attacking people!
W: Oh, don’t be so silly! Of course you wouldn’t.
