Patient

D'agate can be careless in making conclusions that are not true at all, and then getting nasty and demeaning when his error was noted to me. I had noted that my father had a myocardial infarction when he was 64 years old, and D'agate incorrectly concluded that my father had died at age 64. When this error on the part of D'agate was pointed out, instead of acknowledging his error, D'Agate became abusive to me, changing the subject, and challenging my right to point out errors in my family history. I then told him I did not want to have any further professional relationship with his medical practice.
