I find it more off putting that the therapist somehow thinks I care much what they think about me than whether what they say is sincere or not. If what a therapist says helps you, then good. I usually think it insulting for them to engage with me n that fashion. One time, a while back, the woman said something and I responded and she sId she was about to say something nice- I did have to laugh at that and told her the prospect of her saying something nice did not change my position.
