"Dickens had all his life the faults of the little boy who is kept up too late at night. The boy in such a case exhibits a psychological paradox; he is a little too irritable because he is a little too happy. Dickens was always a little too irritable because he was a little too happy. Lie the over-wrought child in society, he was splendidly sociable, and yet suddenly quarrelsome."
