I don't think it is idealistic to think or expect your T not to lie to you. If my T lied to me I would have a really hard time just accepting it without understanding why. There have been a few times where it FELT like my T was lying or had lied about something in order to get me to talk more. These were very small "white" lies but they seriously affected my ability to trust her. Luckily, most of these situation were not actual lies. I don't think my T lies it more like she misleads or allows me misintrepret something until I speak up and challenge or seek clairification.

T are human, but I think they have a special responsibility to be honest with clients even when being so can seriously unsettle them. To me that is therapy, hearing a truth and then working though dealing with it.
