Married members of HN, what did you do if you think diamonds are utterly ridiclious however due to societal constraints some kind of ring is required for your SO?
Honest question: Why marry in the first place? Why practice a personal relationship in a way others have designed? Isn't it somewhat contrary to the theme of Hacker News? To me, the term "hacking" describes the habit of doing things in a more interesting/efficient/fun way than how they are usually done.
From a practical point of view, once kids where involved and we started looking at things like inheritance, it turns out that many things would be much quicker and easier, legally, if we where married if one of us got very sick or died (in our particular jurisdiction).
