May 14, 2012. My mother was 90 yesterday which was a Monday. I saw her on Sunday, Mother's day. I told her ohhh about 6 times that Monday was her birthday and everytime her response was are you sure? I am positive it was long ago. I would tell her that she was going to be 90 and she said she's ready to die. I told her that her son and his wife, were planning a party for her on the 19th, and she said I won't be there I am going to die. I told her that her daughter in law would be very angry since I am sure she ordered a lovely cake from publix for her. ( am being facetious.) Told her that her brother was coming with his wife and one of his 8 kids. She said my brother??? do i have a brother? you mean Tony? I said no Tony is your son, ohhh she said. I said Don is your brother. She said I can't get a picture in my head of my brother. I said thats okay you will recognize him when you see him. She said you need to be there to say look mother here is Don! here is Babette... so I don't seem to look stupid.  My mother was born in 1922, prohibition, the depression, WW II, Korean War, Vietnam, all the others, TVs, electronics, indoor plumbing, just a myriad amount of inventions that she saw come into her life.  
I cannot imagine trying to conjure up a face of a loved one and not being able to do it. I cannot imagine wanting to say something and something entirely different comes out of your mouth and you either laugh or get mad about it. My mother turned 90 and while she has not always been the kindest person to me, she was better than her mother. She has now lived longer than anyone on her side of the family. She has a baby brother that is 85. 
The dementia worsens, her feet and ankles are swollen alot, she doesn't get near the exercise she did here in the house. No on is paying attention to this but me.  I wish I could win the lottery and then I could afford to buy a house with a wing just for her and someone to take care of her in the last part of her life. 
Happy Birthday Mother, I am glad you are still with us, even if you don't know all of us.
