Writers, especially new writers, are often told write what you know, which must have been  Eugene O’Neill’s motto. The Irish-born American Playwright of Long Day’s Journey Into Night clearly had no compunction about heavily mining his life experiences and those of his parents, as the play is very autobiographical. The quadruple Pulitzer Prize winning playwright doesn’t spare himself or any of the protagonists who are easily identified as his mother, father, a brother, himself, his son and wife. So why did he instruct his second wife not to allow it to be performed for 25 years after his death?
