               ” Oh, you know who I am. Interesting.
     The last thing I’ve w r i t t e n into my journal about you - or about the
          younger you - is the nice little encounter with the Silence
       in United States. You must enjoy the privilege of k n o w i n g,
                     since you know things I don’t. “

“A rare occurrence, really,
                whether you’re from my future or not.
       I’ll try not t’ let y’ in on
                   anything too big - but then again…
          Y'can see for yourself that
                     I’ve suffered a change of face since we last met.
      But still alive and kicking,
                                I can assure you, Professor.”
