John: I don’t make it in this house; I don’t know where the things are kept.
Colin: Well, could you go and buy some cigarettes?
John: I’ve got some!
Colin: Could you run out and post a letter?
John (with a grin): I haven’t got any to post!
Colin: Then go out into the street, and go up to the first person you meet, and ask them to teach you to take a hint.
John: You want to be left alone!
Colin: You’re very bright this afternoon.
[John goes straight out of the room.... A sudden silence falls.... Colin takes out his cigarette-case, and helps himself to one; and puts it back ... and takes it out again.
I beg your pardon ... will you?
