This isn't my story but I thought it well worth sharing. I am elderly and sometimes very simple things can get out of control. .
My neighbor was telling me about his parents who are both 89. They live in their own house but have four children here who can look after them.
His mother fell in the den and couldn't get up. She called her husband. Husband was not wearing his hearing aides and watching television. He had the volume turned up so that he could hear the TV. Mother called but she didn't get an answer. She called many times and husband couldn't hear her.
So Mother decided to press the call button on her lifeline. The life line people called and of course the husband answered the phone. He doesn't know his wife is in trouble so he says everything is fine and goes back to watching TV.
It's a good thing there was somebody on life line who was pretty sharp and thought something was wrong.
The life line people came about five minutes after the phone call and got things sorted out.
So with us elderly people things can get out of control in a hurry.
I imagine Dad got told to always wear his hearing aids.
