Plato, Letters 362e

εἶναι.τὰ μετὰ ταῦτα περὶ Δίωνος λέγοιμʼ ἄν. τὰ μὲν ἄλλʼ οὔπω ἔχω λέγειν, πρὶν ἂν παρὰ σοῦ ἔλθωσιν αἱ ἐπιστολαί, ὥσπερ ἔφης· περὶ μέντοι ἐκείνων ὧν οὐκ εἴας μεμνῆσθαι πρὸς αὐτόν, οὔτε ἐμνήσθην οὔτε διελέχθην, ἐξεπειρώμην δὲ εἴτε χαλεπῶς εἴτε ῥᾳδίως οἴσει γιγνομένων, καί μοι ἐδόκει οὐκ ἠρέμα ἂν ἄχθεσθαι εἰ γίγνοιτο. τὰ δὲ ἄλλα περὶ σὲ καὶ λόγῳ καὶ ἔργῳ μέτριός μοι δοκεῖ εἶναι δίων.

good for your reputation nor honorable. In the next place I shall speak about Dion. Other matters I cannot speak of as yet, until the letters from you arrive, as you said; with regard, however, to those matters which you forbade me to mention to him, I neither mentioned nor discussed them, but I did try to discover whether he would take their occurrence hardly or calmly, and it seemed to me that if they occurred it would cause him no small vexation. As to all else Dion’s attitude towards you seems to me to be reasonable both in word and deed.
