I think they are used to putting everything off on the client. The last one I saw apologized for disappointing me, but I hadn't felt disappointed at all. It wasn't until after she moved and I found out that she'd misled me that I realized she'd disappointed herself and shoved that off on to me.

Maybe some will admit it when it's their fault, but I think that's rare. The one I see now did something that was not a terribly bad thing, but she was quick to take responsibility for it and meant it. It was almost worth going through the whole thing just to have that experience of a therapist who owns up to making a mistake.
