Oh sure, I have thoughts on this!
Marriage for me was a natural order of things...very simple we fell in love, lived together for a year and married.
That part's simple...what gets complicated is the re-introduction of the individual personalities and how they blend together over the years.
The piece of paper is archaic, to be sure, but what it represents is like all time honored traditions...a respect for the past and a hope for the future.
When you finally realize that your spouse is not put on this world to live up to your expectations (and you are not put here to live up to hers), then you cherish the few times you come together and actually share the important, beautiful parts of life.
They are fleeting, to be sure, but they are worth it.
