I've just watched the timestamp at 18 mins into the vlog where Nadia hysterically shouts re wanting coffee. I genuinely don't know if she's acting? Her eyes look really vacant though. It's a strange one.
Part of me thinks the whole household screams and shouts at each other far more than they talk to each other.
Shes definitely having some kind of child like temper tantrum.
I found this online
"Seniors throw temper tantrums for a whole host of reasons. Often, it’s a result of the personality changes brought on by Alzheimer’s disease and other forms of dementia"
