STEPHEN. Not at all.

UNDERSHAFT. Mr Cusins: I am much indebted to you for explaining
so precisely. [Turning to Sarah] Barbara, my dear--

SARAH [prompting him] Sarah.

UNDERSHAFT. Sarah, of course. [They shake hands. He goes over to
Barbara] Barbara--I am right this time, I hope.

BARBARA. Quite right. [They shake hands].

LADY BRITOMART [resuming command] Sit down, all of you. Sit down,
Andrew. [She comes forward and sits on the settle. Cusins also
brings his chair forward on her left. Barbara and Stephen resume
their seats. Lomax gives his chair to Sarah and goes for
another].

UNDERSHAFT. Thank you, my love.

LOMAX [conversationally, as he brings a chair forward between the
writing table and the settee, and offers it to Undershaft] Takes
you some time to find out exactly where you are, don't it?

UNDERSHAFT [accepting the chair] That is not what embarrasses me,
Mr Lomax. My difficulty is that if I play the part of a father, I
shall produce the effect of an intrusive stranger; and if I play
the part of a discreet stranger, I may appear a callous father.
