Calumniae non temere credundum

The saddest thing of all is that the slandered man, unaware of all that has taken place, meets his friend cheerfully, not being conscious of any misdeed, and speaks and acts in his usual manner, when he is beset on every side, poor fellow, with lurking foes. The other, if he is noble, gentlemanly, and outspoken, at once lets his anger burst out and vents his wrath, and then at last, on permitting a defence to be made, finds out that he was incensed at_ his friend for nothing.
