But as time went on he gradually showed a disposition that was averse to idleness, effeminacy, wine-bibbing, and money-making; and by preparing his oratory to waft him as on swift pinions to public life, he made it clear that he was not going to remain quiet;
and in defending Vettius, a friend of his who was under prosecution, he had the people about him inspired and frantic with sympathetic delight, and made the other orators appear to be no better than children. Once more, therefore, the nobles began to be alarmed, and there was much talk among them about not permitting Caius to be made tribune.
