So if he can't remember that, he's senile, old, degen, and unqualified.
Maybe there are so many intimate partners that he cannot keep track of them all.
My mom had dementia. For her last few years, she couldnt remember who I was, and how did I know so much about her, her home, and her family?
So Joe honestly saying he doesnt remember Tara Reade indicates that he is very much suffering from dementia, because as you mentioned, he would remember that kind of intimacy.
He is unqualified in so very many ways.
I can't, but have an excuse. Uncle stationed me in Bangkok for over three years.
That said, I'm reasonably sure their names were either, Lek, Noi, or Dang.
