This must have been covered in the fellowship year if you did peds because no one in all her years of training had ever suggested to her that she call a patient’s parent Mom. If anyone had, she would have explained that its subtext—you know less about your child than I do, for I am a trained professional and also because, as a woman, you are slightly hysterical—was offensive, untrue, and frankly embarrassing for the physician.
