She is entering late stage Parkinsons I am almost sure. I will bet she has known that she has Parkinsons from as far back as 2005.
When she waves both her hands around when she speaks it is because she can’t hold them still so doesn’t want to get caught having them shake. Watch her hands every time she speaks. The middle finger over the index finger is apparently a sign.
She will also press her whole right hand flat against her chest at times to keep the fingers and hands from shaking.
I think she was drunk.
