Dump the old lady off

Wow!  It's hard to believe the nerve of some people but the world is full of jerks.
    My Mom is 89 years old, deft, and legally blind to the point of only being able to see fuzzy shapes.  In October he fell asleep while trying to fry a hamburger patty and set the fire alarm off.  She has little control of her bowels and suffers from various aliments.  A week after she set the alarm off she fell and sat in the floor for several hours until she could reach a phone.  She managed to get to the door but couldn't open it so the rescue squad had to break into her home. 
   My younger brother wanted to move her to Savannah, Ga. to stay with him so he packed her up and took her away on my birthday.  Well, that should have been a happy ending for all concerned but it wasn't.
  It seems by little brother decided to leave the care of his mother to his wife and daughter.  Mom is a difficult person to get along with.  She is as sweet as she can be but she likes to talk, like no stop, and she is fiercely independent and she is very particular about what she likes and what she doesn't and s.  she will tell her friends about things.  If one is sensitive, and most people are, then one is better off not getting involved with Mom.  She is as good as gold but she will grate on a person's nerves, telling the same stories over and over talking about peoples faults and shortcomings.  Her biggest fault is she doesn't like to admit she has made a mistake. 
  Even so, I think the situation she has found herself in is deplorable.  Her daughter-in-law found it hard to deal with Moms talking and her dirty diaper pail and her complaining about missing home and leaving her friends.  The last straw for her came when she overheard Mom complain to one of her friends (over the phone) that she had been left alone with no food in the house.  She was justified in her decision to become upset at Mom's behavior.  Old people can be hard to deal with and the job should not have been hers to begin with.
   Little brother, on the other hand, had delegated his responsibility to her and his reaction to his wife becoming upset was to pack his mother and her belongings and drop her back in Hickory.  There is no food in the house and no telephone.  No one knows she is there but  me and my older brother and he doesn't care.    The worse part of the deal is he gave no thought to working out a solution to the problem nor discussing a timeline with me.  She drive her home and dump her off. 
   To me, he's always been a jerk and I believe he still is.
