If at the onset of the therapy treatment, you have diagnosed your client as a Delicious apple, then at the conclusion they might become a Macintosh apple, BUT, rarely a Banana.
A client’s behavior is always correct. Not good, and not bad. Just the best one can do at the moment. That applies to lying, swearing, hitting, singing, dancing, sulking and refusing to eat Kale!
The psychotherapist must be curious. Absent curiosity, most therapy sessions will be boring, even for the client.
When a client enters the therapy session, they will tell you the truth. Albeit, their truth. The search then begins for both you and the client.
