I told them they had taken what I said about a critical time win- dow far too lightly generic female cialis 10 mg line. I did not know if the window was three months or two months or just two weeks. I wanted Marie to go to physical therapy twice a day, take naps, do no reading, watch no television, and make no phone calls. She was to convalesce in quiet and peace if she was to get well ahead of schedule. I insisted on removing all contact with her friends and lim- iting family contact. Te next day, they called me to physical therapy and told me that Marie had actually walked a few steps. I said that was just a ﬂuke and did not mean anything and left immediately, waving at Marie without talking to her. On the ﬁfth day, Marie stood in one corner of the physical therapy room and suddenly began to turn cartwheels across the mat. None of my terms had carried speciﬁc meanings, yet all sounded like I was being very speciﬁc. I stated everything in a way that was plausible and in a way that could not be directly refuted. Te only action I really took was to withdraw her from all friends and from all entertainment. She went into a long discus- sion of how thankful she was that Marie was healed. She expressed a sincere belief that God had healed her and that I had not got in the way of God in the manner those other doctors had. I thought to myself that hers might be one of the highest com- pliments I had ever received, even though I would not have thought of it in the same terms. In the patient I am now going to discuss—I will call her Regina— some will say that I went too far or that I should not have done what I did. Te orthopedist knew of my interest in diﬃcult patients and asked me to see her to ﬁnd out if I had anything to suggest.
