Meaning of sub-plot

Rating: 8/10 (23 October 2005)

From what I know of George Clooney, he tries to make a point with everything he does. I'm wondering what the point of the sub-plot about the secretly married couple was supposed to be. I think it might have to do with the hypocrisy of our culture in the '50's, but I can't quite put my finger on it. Any ideas?
Now I'm wondering why there's a need for a minimum of 10 lines to submit a comment, but yet a warning about padding. When I tried to submit the above comment, it was rejected for not being long enough. Is this another example of hypocrisy? I'm a very direct person who likes to be brief and concise. What's wrong with that?
