Okay, get this one for a character:
Personality trait[s]: gets angry when patient calls her more than one time; after this, nurse will make patient wait until patient has called several times before going to see about him/her and when nurse goes to see about the patient, will accuse patient of not doing as told or something appropriate to the action under consideration.
3 doctors on case because patient needs primary care doctor, kidney doctor, and a liver doctor
Personality trait[s]: don’t consult each other before telling the patient his/her findings; either one can/will tell patient patient is dying while one or the other of the three left to speak will say the patient is getting better. OR make each say something different, for example:  You’re dying. The liver has quit functioning properly, therefore the kidneys have failed as a result.  Although you’re in critical shape, if we [_____], you will soon be on your feet again.  Sorry, sir/miss, we haven’t received all the results of your tests yet so it’s difficult to make a diagnoses here. AND let those messages to to patient in the same day.
Yep, based on a true happening, but what the hey, isn’t all fiction based on non-fiction somewhere along the line?
