all right, you know.

CUSINS. Let me advise you to study Greek, Mr Undershaft. Greek
scholars are privileged men. Few of them know Greek; and none of
them know anything else; but their position is unchallengeable.
Other languages are the qualifications of waiters and commercial
travellers: Greek is to a man of position what the hallmark is to
silver.

BARBARA. Dolly: don't be insincere. Cholly: fetch your concertina
and play something for us.

LOMAX [doubtfully to Undershaft] Perhaps that sort of thing isn't
in your line, eh?

UNDERSHAFT. I am particularly fond of music.

LOMAX [delighted] Are you? Then I'll get it. [He goes upstairs
for the instrument].

UNDERSHAFT. Do you play, Barbara?

BARBARA. Only the tambourine. But Cholly's teaching me the
concertina.

UNDERSHAFT. Is Cholly also a member of the Salvation Army?

BARBARA. No: he says it's bad form to be a dissenter. But I don't
despair of Cholly. I made him come yesterday to a meeting at the
dock gates, and take the collection in his hat.
