Beware the high-functioning, white habituated Nigress. 
They are exceptionally rare. But they exist. 

I once knew an English Lit black girl, who took a fancy to a friend of mine, drop her minor, self educate herself in basic programming, just to be in the same class as him, and successfully bushwack a gormless yet study white man into a committed relationship. 

0.01%  top talent Negresses, they can and will crawl through broken glass for white bf.
