Never in my life have I given a truthful answer to this question, not because I could not find the words to describe how I was feeling, but because I did not even know how I was feeling. And I have no answer then either. This is how purely private I am. Not like the privacy I experience when I am alone in a quiet room, but absolutely pure privacy. So pure that at times I can find privacy from myself.
Pure privacy is universal.
Therefore every individual is equally private yet purely public. Somewhere in the psyche of every person is the knowledge that we are all different. This is what makes privacy universal. For if one's privacy were not in some way known by someone else, it would no longer be private.
