Livia lost her son Drusus, who would have been a great emperor, and was already a great general: he had marched far into Germany, and had planted the Roman standards in places where the very existence of the Romans was hardly known.
He died on the march, his very foes treating him with respect, observing a reciprocal truce, and not having the heart to wish for what would do them most service.
In addition to his dying thus in his country’s service, great sorrow for him was expressed by the citizens, the provinces, and the whole of Italy, through which his corpse was attended by the people of the free towns and colonies, who poured out to perform the last sad offices to him, till it reached Rome in a procession which resembled a triumph.
His mother was not permitted to receive his last kiss and gather the last fond words from his dying lips: she followed the relics of her Drusus on their long journey, though every one of the funeral pyres with which all Italy was glowing seemed to renew her grief, as though she had lost him so many times.
When, however, she at last laid him in the tomb, she left her sorrow there with him, and grieved no more than was becoming to a Caesar or due to a son.
She did not cease to make frequent mention of the name of her Drusus, to set up his portrait in all places, both public and private, and to speak of him and listen while others spoke of him with the greatest pleasure: she lived with his memory; which none can embrace and consort with who has made it painful to himself. 
Choose, therefore, which of these two examples you think the more commendable: if you prefer to follow the former, you will remove yourself from the number of the living; you will shun the sight both of other people’s children and of your own, and even of him whose loss you deplore; you will be looked upon by mothers as an omen of evil; you will refuse to take part in honourable, permissible pleasures, thinking them unbecoming for one so afflicted; you will be loath to linger above ground, and will be especially angry with your age, because it will not straightaway bring your life abruptly to an end.
I here put the best construction on what is really most contemptible and foreign to your character.
I mean that you will show yourself unwilling to live, and unable to die. If, on the other hand, showing a milder and better regulated spirit, you try to follow the example of the latter most exalted lady, you will not be in misery, nor will you wear your life out with suffering.
Plague on it! what madness this is, to punish oneself because one is unfortunate, and not to lessen, but to increase one’s ills!
You ought to display, in this matter also, that decent behaviour and modesty which has characterised all your life: for there is such a thing as self-restraint in grief also.
You will show more respect for the youth himself, who well deserves that it should make you glad to speak and think of him, if you make him able to meet his mother with a cheerful countenance, even as he was wont to do when alive.
