It wasn’t the boy I had a problem with. It was his mother.
We had met a few months earlier, when I gave her 14-year-old son a diagnosis of mild asthma. I didn’t mind her tough questions, but her tone of voice put me on edge. She seemed suspicious, almost angry. Still, in the end I decided she was just a smart, assertive parent, and I let it go.

I have had my share of difficult patients and parents. But putting up with this lady had taken more time than it was worth, and it interfered with my taking care of her son. I wasn’t sure I wanted to do it again.
I considered my options. I could be stoic, do my job and keep the boy in my practice. I could call his mother and ask her to keep her opinions to herself so I could focus on her son, though my instincts told me that this wouldn’t stop her. Finally, I could decline to see her son, and therefore her, ever again. In other words, fire my patient.
