The bad news:
Grandma has Parkinson's disease. She was diagnosed today.
She's also been declared a ward of the state of Texas, and has been deemed unable to properly care for herself. She's being placed in a nursing home, and will not be allowed to return home. This has been explained to grandma, but she's still convinced that she's going back home.
The good news:
I have placed one of my avocado trees in a pot. I am quite happy with myself.
