Never call yourself a philosopher, nor talk a great deal among the unlearned about theorems, but act conformably to them. Thus, at an entertainment, don't talk how persons ought to eat, but eat as you ought. For remember that in this manner Socrates also universally avoided all ostentation.
When something tragic has happened, you can try to move on and put something tragic behind you, but it rarely works. It's in you when something like that happens. It's physically a part of your life.
