Wars have been fought over people who love themselves protecting themselves and their rights. They aren't trying to clash... but are brought to a conflict by a difference of opinion.

When a doctor tells you to do something, it generally is not a request. Know the expression "doctor's orders"? Telling them "no", regardless of one's motives, and regardless of one's relative comfort doing it, is, IMHO, a confrontation.

That is how I see it, but I will happily agree to disagree on the term "confrontation" and its use.

The point remains:

Bizi is uncomfortable with [pick your favorite term to indicate the interaction where she tells the doctor "no"].
