She doesn't look or sound tired to me. She looks very sad at times.
Screen captures are hard to tell how anyone looks regarding any emotion. It could be a split second of a change of discussion.
That's her "Mama Grizzly" face.
And as a certain Civil War General said, I believe Sarah will say of those Democrat sub-human vermin who attacked her, and her family in the most vile terms possible,
"May God have Mercy on General Lee, for I will have none."
Cheers!
