I'm the second of three generations of nurses, and let me tell you, I (we've) messed up many a meal with other "civilians".
My wife gave me an elbow to the ribs one night, pointing out that one of our dinner partners was turning green.
All I was doing was talking about a cervical fx pt I was taking care of, and how they put the Crutchfield Tongs in!!!!
Ok, Ok, the diagrams on the place mats was a wee bit overboard!!
But many time, mom, my daughter and I go off on a subject at the dinner table, and I know the others would be happy to get out of earshot!!!
Another problem, if you are at some sort of social gathering, say a grade school play, and a medical problem pops up.....do you get involved???
I've done it both ways, and my family gets upset.
The situation is under control, I keep my seat, and they get mad.
I get involved, and am busy for a while, miss the event, and they're mad.
As I've gotten older, I hesitate to give a family member a "diagnosis". I'll give my opinion if asked, but I try to maintain an even keel as it were.
Not in an emergency mind you, but the basic, "what does this rash look like to you?" or "what does a TB cough sound like?" type stuff.
