Alice, your father is amazing. He's 90 years old and he lives alone in that big house.
I know. He doesn't like to ask anyone for help. My dad insists on paying his own bills and taking care of himself!
That sounds like my Grandmother. She was always stubbornly independent.
It seems that folks like my father and your grandmother are determined to be on their own.
They see their independence as a kind of character strength.
Sometimes they are too independent.
