I have never known any who could/would state specifics. Being ambiguous means you can't pin them down when it fails and they get to blame the client rather than themselves. It is not a practical way of solving problems. I finally quit using it for the reasons I sought it and found a different purpose that I am willing to pay for - but it is not what the therapist first said she could do (she couldn't) or anything practical or directed at why I went in the first place.
