All of my T's including my addictions nurses say that if they see me in public they won't acknowledge me, unless I initiate it. Seems to be fairly standard practice to protect confidentiallity / annonymity.

It's only really an issue with one of my T's. My primary T who I've been seeing the longest have a mutual acquaintance who is a musician. We both always go to her concerts. My T won't initiate, but I usually go over to her to say hi and we talk about the concert. It was a little weird when she introduced me to her partner. (oh right T does have a life outside of therapy).
