This is her milieu.
An experienced professor in a classroom.
These are her students.
She knows how to focus the dialog and sell her message.
I have a different take on her delivery. She’s a teacher? A teacher knows how to speak with full voice and authority. she is putting on the little girl weepy voice. It’s not even a good act to those of us who know real from acting. Men are so gullible when it comes to women. Get it guys! Never approach a women expecting logic. Sorry gals, you know i’m right.
