The "Portrait of Dr. Gachet" (2nd Version)

While The Starry Night is my favorite Vincent van Gogh piece, The Portrait of Dr. Gachet (2nd version) is an extremely close second.  Van Gogh painted his particular facial expression... perfectly. His face is the focal point of my entire life.  What can you say about the face Dr. Gachet is making? Kind? Loving? Serene? Caring? Firm? Sad? Happy? Compassionate? Understanding? What about the emotional/mental/spiritual/physical workings inside the mind making that face?  Who is he facing? (Well, he technically faced van Gogh for the piece...).  Have you ever made that facial expression before? How about towards yourself? How about making that face to God? How about Jesus making that face to you? How about your spouse making that face to you? How about your boyfriend/girlfriend making that face to you? How about your brother/sister/son/daughter making that face to you? What would it mean to you if someone made that face to you?

What causes a person to make that facial expression? 

Van Gogh knew.  He's asking us if we know.
