if skr had during therapy said that to me I would have seen no problem with it. In fact SKR and I had this type of therapy relationship where we used terms like being a turd. lots of times I jokingly told her things like so you thought you were a real smart *** like I did huh and shed say something like yup she was like me a real turd.

the responce is just acknowleging to the client that they see things the same way that the client did - that they thought they knew everything and then later got proved how foolish their thinking was.

Some people have that type of relationship where they can banter back and forth like this with each other in the client therapist relationship.
