When we terminated the first time after 9 years my T, as I was leaving the last session, put her hand on my shoulder and squeezed. I didn't wash that shoulder for years LOL :-) But we never hugged and I guess I would have found it awkward as she was so much "smaller" than I am. I think in our cases it is just as hard for the T to initiate the hug since we probably give off "unsure" vibes :-) and they don't want to be rejected either or make things worse by "misreading" us.
