a friend is a second self - Cicero

Optime autem societas hominum conjunctioque servabitur, si, ut quisque erit conjunctissimus, ita in eum benignitatis plurimum conferetur. (...)

Homo, qui erranti comiter monstrat viam,
Quasi lumen de suo lumine accendat, facit
Nihilo minus ipsi lucet, cum illi accenderit.

We ought, then, to set up images of a kind that can adhere longest in the memory. And we shall do so if we establish likenesses as striking as possible; if we set up images that are not many or vague, but doing something; if we assign to them exceptional beauty or singular ugliness; if we dress some of them with crowns or purple cloaks, for example, so that the likeness may be more distinct to us; or if we somehow disfigure them, as by introducing one stained with blood or soiled with mud or smeared with red paint, so that its form is more striking, or by assigning certain comic effects to our images, for that, too, will ensure our remembering them more readily.

When the young die I am reminded of a strong flame extinguished by a torrent; but when old men die it is as if a fire had gone out without the use of force and of its own accord, after the fuel had been consumed; and, just as apples when they are green are with difficulty plucked from the tree, but when ripe and mellow fall of themselves, so, with the young, death comes as a result of force, while with the old it is the result of ripeness. To me, indeed, the thought of this "ripeness" for death is so pleasant, that the nearer I approach death the more I feel like one who is in sight of land at last and is about to anchor in his home port after a long voyage.
