How does one deal with the constant pressure of a patient who thinks he is right?

Has this person always been right, or is this a new conviction since the stroke?

Definitely need more info.....

I had a roommate once who was "always right." One time, she insisted a city was in a certain place, but she was wrong. When I pulled out the atlas to show her, she refused to even look at it.....she just kept insisting she was right! Sometimes there's no fixing stubborn....

Sounds like my Mom, FIL and husband...LOL I think we need more information here!
