I am caregiver for my 83 year old wife. Besides her physical inabilities, her memory is biggest impediment to normalcy. We sit and watch TV a lot, and her senseless dribble is pretty grating. I can hardly watch TV for her talking constantly...about nothing, mostly. Sometimes it is interspersed with intelligent observations, but mostly memories from her childhood. I manage to keep my composure by research on my laptop, as well as social interaction on FB. I could tell she resented my talking on Facebook and not listening to her. It has come to a point where we have angry disagreements and she gets mad and goes to bed. (She has a TV there). I know others have this problem and wonder how to handle it diplomatically. Maybe she will eventually get over it. Her dementia gets worse, then better. Not giving up my contact with intelligence!
