Fathers do not exasperate your children;
instead, bring them up in the training and instruction of the Lord. Ephesians 6:4
It is a lonely existence to be a child with a disability which no-one can see or understand, you exasperate your teachers, you disappoint your parents, and worst of all you know that you are not just stupid.
Bad people are, from the point of view of art, fascinating studies.
They represent colour, variety and strangeness. Good people exasperate one's reason; bad people stir one's imagination.
