Well, you are lucky to be acknowledged by your T out of session.

I saw my T at a supermarket once, I wanted to run up to him and hug him and all that, but he completely blanked me. That really hurt.

Then I asked him in a session why he did that. He said that most people don't want other people to know about them having a therapist so he never says hello to any of his clients.

Just made me realize that I am nothing really to him.
