She reminds me of Tom Hanks crazy secretary in the movie Splash. The one who showed up to work wearing her bra on the outside of her blouse. Her crazy was in full view but, no one said anything.
So many blacks have white blood, I guess there was no diplomatic way to bring it up. I work with a woman who identifies herself as black but she is practically white. She does have black features though (it isn’t spray-tan).
