As a friend, you can be the imperfect doctor with the imperfect patient, so forgiveness is implied in all actions. And what comfort to the patient in knowing that a friend is on the case, a chance to feel special. That feeling alone is good medicine. In the current climate of litigation, the health professional can, too, feel great comfort in entering a patient's room knowing that, at least here, they can feel safe. Transference in inevitable.
Every object has some kind of impact on another.
Some studies have shown that just the doctor's presence can have a positive impact on the patient's health. It goes without saying that the deeper the friendship, the deeper the effect. So I would love them. As I loved them so, too, they would love me. This is good stuff because if the love is present and real, then a patient cannot say 'I am alone', which matters greatly to them and to me.
