A response to a story - a portrait of P

Sitter 2, photo 1
I am tuning my natural portrait studio.  I have got a task to take the official portrait of the Vice-Chanchellor of Helsinki University. Therefore I ask some people to sit for me.  P is my former colleague and good friend.  Here P:s gesture is a response to my story.
