The black kid went to the bathroom and painted his face in white using water paint: All was white, not even a black spot appeared.
He rushed to the mother and said, Mum, look!
She said, What have you done, damn kid!? Go back to the bathroom and wash your face immediately!
Not conforming, he rushed to the father and said, Dad, look!
He said, What have you done stupid kid!? Go immediately to the bathroom and wash your face entirely!
He then said to himself, Oh, not even two minutes that I am white and I already hate two blacks.
