Throughout the play, O'Neill's theme is one of a disclosure into the life of a seemingly normal family on the outside yet convoluted with bitterness on the inside. It portrays the actions of a dysfunctional family and brings us on a reflective journey from when the fledgling family had started, devoted to one another with high hopes for the future, to what it is today, a family engulfed in turmoil. "Who would have thought Jamie would grow up to disgrace us Its such a pity You brought him up to be a boozer." (110) In this excerpt from Mary's conversation with James regarding their son, it is obvious that their life had taken a 180-degree turn from when their offspring were mere children with promise.
Characterization throughout the play helps us not only to understand the characters' actions but also to see into the soul of each and to comprehend their thoughts and emotions, essentially assessing the motives for their actions. Early in the play, Mary is perceived to be a common, traditional housewife "She is dressed simply she has the simple, unaffected charm of a shy covenant-girl youthfulness she has never lost-an innate worldly innocence." (13) Yet as the play progresses, she is portrayed in a different light. "I hope, sometime, without meaning it, I will take an overdose. I never could do it deliberately. The Blessed Virgin could never forgive me, then." (121)
