I think it best when a client sees it and recognizes such things. It gives the client knowledge and power. I don't see it as dishonest when everyone knows they are doing such a thing. They are trained to try to do that sort of thing at clients. It is, from what I have read and seen, their main goal.
If you don't like it - then it would be freeing, it seems to me, to just go in and be however you like without regard to the therapist at all. Take control - don't let her reactions control you.
