Be happy, beloved face of my great friend. For us that is impossible, but you can be-we dead lack any source of delight - Euripides

What heavenly power lends an ear
To a breaker of oaths, a deceiver?

O making of children, hapless work, sorrow of mankind, the man who reasons well will live his whole life childless and not risk having children whom some day he must bury.

But I wish to give you a wise piece of advice. When a friend is enraged with a man his friend, having met him face to face, let him fix his eyes on his friend's eyes, this only ought he to consider, the end for which he is come, but to have no recollection of former grievances.
