Was like the Star Trek Episode "Whom Gods Destroy". Took my mother to see the eye doctor. She was hurling insults at the nurse making appointments etc. The nurse said, after check-in, the doctor will be with you in several minutes. (We waited 5 minutes). My mother yelled out "OH SURE." I took her home to my house after the doctor's visit. She demanded cereal with strawberries. I was able to give her Cheerios. I attempted to have her sit on the couch in the living room. I started watching "The Science Channel" while she made a mess with the cereal. In response to the NASA TV program, she asked me "what is a planet?"; "whyt are they there?"; "why did it take so long to get to Pluto?". Round and 'round we went. I broke that cycle. Then she got on "Adolf Hitler was a bad man." And we went 'round and 'round on that until I broke the cycle. She also said, "I'm NOT GOING TO DIE IN THAT NURSING HOME. YOU THINK ABOUT THAT,". I took her to get some lunch. She kept insisting she didn't need the walker (which is required.) I managed to get her to the table. After lunch, I guided her back to the car. I let go of the walker to open the door from the restaurant - and she falls over backwards. WHAM. As you can imagine, this was becoming a nightmare. She was OK after that fall. HOWEVER, I reported this to the nursing staff. My mother then got mad at me and started dialing my cell phone and hanging up. Needless to say, I had to put some space between her and I. Any insight?
