I think it just sounds so dismissive, if I'm imagining correctly what you are all describing.

It's as if I had a guest in my home, and it's time for them to leave. They know they need to leave and I know, but I still would walk them to the door and say goodbye. I wouldn't just dismiss them from my living room by waving them towards the door as I grabbed the phone to do something else. Even when I have people over that I *really* want to get rid of, I walk them to the door and say goodbye! Even when my mom, who stresses me out to no end, decided to extend her stay an extra day and leave at 6am (way before my normal wakeup time) - I set an alarm, got up, and walked her to the door to say goodbye. Is that not normal behavior? (The only time I can think of when I haven't done that was when a friend brought me home from minor surgery. He helped me get up the stairs and into bed. It would have been silly for me to walk back downstairs and risk falling over to let him out... so he let himself out and locked the door behind him.)

It's not that I think they should extend their time. I just think it's common courtesy to actually stay present until the interaction is actually over. It sounds like these T's think the interaction is over because the time is done, but in reality, it's not really over until you're outside of their personal/office space.

Once I step outside of the door to my T's office, I have no clue what she does. She could roll her eyes and let out a big sigh of relief that I'm gone - and that's fine. It doesn't matter, b/c I'm out of her space at that point.

I don't know, maybe I'm just sensitive to the idea of being "dismissed".
