My dear Tiberius, you must not give way to youthful emotion or take it to heart if anyone speaks ill of me; let us be satisfied if we can make people stop short at unkind words.
Aetati tuae, mi Tiberi, noli in hac re indulgere et nimium indignari quemquam esse, qui de me male loquatur; satis est enim, si hoc habemus ne quis nobis male facere possit.
