It's strange how we're all different. I want to call my therapist Dr. because it highlights his/her credentials and deeper knowledge of psychotherapy. I want to look up to my T as knowing more than I do so as to help me with my complex problems.
I also didn't like it when my primary care doc wore shorts and polo shirt in his office.

It so happens my T now is a LMHC, social worker, and the best trained therapist I ever worked with. I want to call her by some title that shows special regard but can't think any that isn't stupid or common.
I always did like calling teachers, nurses, etc by the title, "Miss Lester", or "Miss Butterfield" or whatever, using Miss in front of the last name. It sounds both intimate and respectful at the same time.
