Furthermore, that you were reading the subtitles in a Southern accent is symbolic of your desire to act "childish."
That your wife complains indicates that you fear her disapproval. At the same time, you are "pissed off" because you oppose these norms placed upon you by society.
Hey, if you want a REAL psychoanalysis, go tell this to your psychiatrist! :-P
