“ These people know the reality and laugh at it. Such laughter has little concern with what is funny. It is often bitter and sometimes a little mad, for it is the laugh under the mask of tragedy, and also the laughter that masks tears. They are the same. It is the laughter of people who value love and friendship and plenty, who have lived with terror and death and hate. - , Return to Laughter (1954) ”
