Persōna /pər-ˈsō-nə/(Latin) originally referred to the masks worn by actors on stage in Greco-Roman drama.

Since they had a megaphone type mouth which threw the sound out in an open-air theather. what the sound comes through, that was the mask. ( power through sonar )

When one acts so well, one really believes it is the real self. because the audience and the actor are the same.

So how to be a person, in a way is how to be a genuine fake.
