Xenophon, Cyropaedia
Walter Miller, Ed.

He was, perhaps, too talkative, partly on account¹ of his education, because he had always been required by his teacher to render an account of what he was doing and to obtain an account from others whenever he was judge; and partly also because of his natural curiosity, he was habitually putting many questions to those about him why things were thus and so; and because of his alertness of mind he readily answered questions that others put to him; so that from all these causes his talkativeness grew upon him. But it was not unpleasant; for just as in the body, in the case of those who have attained their growth although they are still young, there yet appears that freshness which betrays their lack of years, so also in Cyrus's case his talkativeness disclosed not impertinence but nai+vete/ and an affectionate disposition, so that one would be better pleased to hear still more from his lips than to sit by and have him keep silent.
