When my daughter was diagnosed with pneumonia (she was very ill, I thought with just a cold and cough; I was clueless, I had never seen pneumonia or experienced it myself), I guess I didn't display enough emotion to the doctor, who called me a few hours later at home, expressing how seriously ill my daughter was, if she didn't improve in the next couple days, to call and bring her back in. This is a doctor who knows me, knows I take good care of my children, and who's never had to treat my children will any other serious illness (before or since). Lack of emotional display does not mean lack of genuine concern. But others may perceive that to be the case.
