As a psychologist, my first job was working in a small clinic.  One of my patients was a pleasant woman who needed emotional support because of some recurring health problems.

After six months of treating her, I was really impressed with my work. In one session, my patient was reviewing her career and personal accomplishments over the last 50 years as a way to boost her self-esteem.

Suddenly she paused and looked at me.  What she said next brought my ego back in line.   "Honey," she asked sweetly, "what was it again that you do for a living?"
