"Now," said Miss Arbuthnot, "I expect you'll want to see your personality-coach." [...]
"Light vivacity, light vivacity, just say it to yourself over and over whenever you're doing nothing in particular - and even if you are."
"But is that really my personality? Is it the real me?" asked Peggy.
Miss Carnegie raised her eyebrows. "Your personality?" she said, then she smiled. "Oh, I see. Oh dear, you have got a lot to learn, haven't you? You're confusing us with the television side, I'm afraid. Screen personality is quite different. Oh, yes, indeed. A few years ago it was sultry, then we had sparkling for a time, then we had a stretch of sincerity - let me see what came next? Oh, yes, smouldering, and, for a rather brief time, ingenuousness - but that doesn't suit modern audiences, silly to try it, really - then there was a spell of passionpent - the audiences liked that all right, but it was exceedingly trying for everyone else. This season it's lightly vivacious. So just keep on saying it to yourself until you come to me again next Wednesday. Light-vivacity, light vivacity! Try to throw your weight a little more forward on your toes, you'll find that'll help. Light-vivacity, light-vivacity!"
And then to her coiffeur, to her facial-artist, to her deportment-instructor, to her dietician, to a number of others, until, finally, to Miss Higgins.
