This story is so damn stupid, I really dont care. Even stupider, is that black people cannot tell she is white.
My only interest in the story is what Ogre asked, is she mentally ill?
I guess..in one sense could say she is having an identitty crises, the same type that teens go through, when they just dont know who they are, and trying to find this out and "fit in"
On the other hand, its a shattered identity crises, where the self identity is completely disconnected from reality (i.e. belieiving you are god, hitler, budda, black, etc)
or like Talented Mr. Ripley..where he changes his identity, to fit the situation for gain (a manipulative chameleon)
If she is white, and truly believes she is black..she may have a mental disorder
If she is white, but playing a ruse..she is a social deviant
