Absence of Agreement

     A chronic truth of my life is that few are willing to say they agree with me. I don't gloat, but as the old Revue goes, "Nobody Likes A Smart Ass."  While  I would maintain agreement should be consistent in this example, no one seems to want to come on board with my conclusion of "ignorance in the time of surgery."
    The patient, in preparation for a surgical procedure, is in that awkward and ignominious position of lying in a bed, attempting to provide some sort of enlightenment that will impact the pre-surgical event.
       As the medical staff is hovering, waiting to spring into action,first order being to insert an I.V. needle, the patient advises, as often in the past, that, "I don't use my right arm."  This is standard medical advice from a trusted surgeon, based on prior surgery that involved lymph node removal. Nothing new here; meaning seems apparent, at least to me.
      But the nurse, or whatever version thereof, immediately proceeds to jab a needle into the patient's right arm. "No," says the patient, "I just said I don't use my right arm." 
      The other nurse person, who seems to be in charge, speaks up, evidently for both of them:  "Oh, we misunderstood, we didn't know what you meant."
     Patient asks, "What did you think I meant?" 
     Nurse responds, speaking in plural pronoun, "We thought you meant you don't use your right hand, like to write something."
    Unbelievably, again at least to me, a trusted and allegedly intelligent family member says he can follow the nurses' reasoning, justifying their reasoning.
    (My conclusion is that everybody hates me.
