'Well, but when they haven't got any----Anyhow, we all do it; one's got to in polite life,' he would aver, defending himself. 'They've mostly got some; and if one's real self sits despising and criticizing, one's outer self has no business to be a decoy. Even if the real self keeps quite behind the screen, it's unfair; and if it keeps looking out, as yours does, it's insolent as well. You insult them by as good as saying, "It's not much of a screen, but it will do for you. If you do see behind it sometimes, it doesn't matter very much; and if the people looking on, who know me better, see behind all the time, it doesn't matter in the least." A screen, to be at all courteous, should be impenetrable both to the people concerned and to the lookers-on; and even then it's not honest--one should quite withdraw.' 'You know, if one quite withdrew from all the people one doesn't quite like, one's world would get very limited.' 'Well, yes'--she wrinkled her forehead in doubt--'only they should know the terms, that's all.' It was probable that Miss Varley might have disapproved of the manner of the homeward journey in the motor, for the Crevequers, who were slightly inexperienced, drove, as they had suggested, by turns; and behind Venables' screen of serenity his real self undoubtedly watched anxiously, and occasionally looked out, betraying itself by the nervous tension of the hands waiting in readiness to seize the wheel; the screen was, indeed, rather insultingly flimsy. They ran along the white coast road, with the gold of the west behind them, and the pale blue winter sea beside them, and the bright city of many hues growing larger in front of them as they circled the bay. They went much too fast, and it was very amusing. 'You must show Baja to my mother sometime,' Venables said. 'She has only visited it with the native guides so far; and you will be able to tell her so much that's interesting and new--very new.' Betty sighed after that renounced game. 'I'm afraid not, do you know.... Tommy, you awfully nearly slew that goat. And I'm sure it's my turn now.' She had swerved from the subject with a laudable impulse of shame, her first in this matter. At the same time, she knew very well that Venables minded nothing; also, that if she had looked at him his amused eyes would have twinkled into hers. That she did not might have been taken to imply in her the rudiments of a growing conscience; or possibly of a feeling that, though she and Tommy might laugh at a person's mother, the person might well keep out of it. His not resenting it--but this she did not word to herself at all, for she would not for some time know it--showed that he accepted so much, easily and without surprise. Why resent that, of all things? it seemed to imply. It was, indeed, hardly worth a comment; it was so wholly in keeping; as he would have said, so obvious.
