Redefining myself

   This is like a crisis of faith, except it is a crisis of self.  Who am
I? Who is the person behind this voice?  Am I the same person I have been
for the past half a lifetime?  Or am I different?  Has this public person,
this person we have known for so very long, been the only person aboard? 
Or has there been someone else lurking, patiently waiting?  Is that person
more fully here now?  Taking an interest?  Interested in taking over?  How
much?
