Real Vs. Virtual old

So I've been thinking alot about this whole virtual real and real self thing.  I wonder about myself now, how much of me is real and how much isn't?  What is it that I want people to know about my real self and my virtual self?  Where do they overlap?  I don't know it seems like we all have things to hide so does the real really exist?  I dont know.... it so confusing.  People in general are confusing and i feel like this just adds another demension of confusion.
