@redheadpei I do not know if that sort of personality was in them all along but have wondered the same thing. My Aunt was just the sweetest person and she did a 100% flip, like you said cursing and just mean. Heartbreaking but my Mother never got mad at her and she would try to distract her from what was making her mad. My Mother is a Saint, I do not know how she cared for these people, also she did not believe in medicating them. She had one lady that kept going out the door so she hung a dish towel over the doorknob and the lady never went out the door again. She could not see the doorknob and to her, it was not a door.
