Letters 58.37
But I am running on too long; and, besides, there is matter here to fill a day. And how can a man end his life, if he cannot end a letter? So farewell. This last word you will read with greater pleasure than all my deadly talk about death. Farewell.
Seneca, Letters to Lucilius 58.37, translated by Richard Mott Gummere
