In session my therapist is warm, friendly, generous in his disclosures (though without being burdensome about it). In person outside of session he is more reserved and quiet so his warmth and friendliness are still there but much more understated.
I don’t see that his affect has changed much over time. In one sense he’s the same as he always was. Very consistent. I have come to know and appreciate him and his affect more and more, and our relationship has grown and deepened over the time we have worked together. So in another sense, he has changed, or my experience of him has changed. But… it all has been very solid, stable and consistent.
