A veteran, calm and assured, he pauses for a well-measured moment in the doorway of the office and then, boldly, clearly, with the subtly modulated British intonation which his public demands of him, speaks his opening line, 'Good morning!'
And the three secretaries - each of them a charming and accomplished actress in her own chosen style - recognise him instantly, without even a flicker of doubt, and reply 'Good morning' to him. (There is something religious here, like responses in church; a reaffirmation of faith in the basic American dogma, that it is, always, a Good Morning. Good, despite the Russians and their rockets, and all the ills and worries of the flesh. For of course we know, don't we, that the Russians and the worries are not real? They can be unsought and made to vanish. And therefore the morning can ve made to be good. Very well then, it is good.
