Relatability

I don't know if it's even a word, but here you'll read it, relate-ability. How does one relate to another? Social skills, communication skills. Can you relate?

From a brief scan of actors over the years, I've noticed that a lot of good actors simply did not know how to communicate off-camera. They are sullen, withdrawn, in their own world, mute. Anti-social. Outcasts. They save all their energy and grace for the camera. They are fine with other people's words but not their own. It's as if they are merely an instrument, a hollowed out one, fine tuned simply by words written down. When it's time for them to be themselves, be with other human beings outside of the camera and lights, they don't know what to do. They are in a trance, as if dumbfounded.

Does becoming an actor fulfill a need to form a union with another human being?

You always hear the joke of the actor who uses other famous words or quotations when they are trying to prove their love in real life to another person -- and the other person goes, "That's from so-and so! Why can't you just tell me yourself in your own words?"
