I can always tell when I am on a different planet..  At times much of the surface looks the same as others...  But its when the stars come out at night..  Misplaced and rearranged they seem.. The stars of someone else's sky reminds me that I am never in the same place.. The constellations all have their stories..  I call it the book of stars.. As it is never ending to all the different eyes that behold them somewhere in time elsewhere...   This star page tells me I am on Earth tonight.. Orion is the first to greet me..  I must continue on..
