A good idea

CHARLOTTE:Shall I make some coffee, Jane?
JANE:That's a good idea, Charlotte.
CHARLOTTE:It's ready. Do you want any milk?
JANE:Just a little, please.
CHARLOTTE:What about some sugar? Two teaspoonfuls?
JANE:No, less than that. One and a half teaspoonfuls, please. That's enough for me.
JANE:That was very nice.
CHARLOTTE:Would you like some more?
JANE:Yes, please.
JANE:I'd like a cigarette, too. May I have one?
CHARLOTTE:Of course. I think there are a few in that box.
JANE:I'm afraid it's empty.
CHARLOTTE:What a pity!
JANE:It doesn't matter.
CHARLOTTE:Have a biscuit instead. Eat more and smoke less!
JANE:That's very good advice!
