Ya, well in my mind getting married makes very little real sense to me. It has more to do with organized religion then it does with praticality. People don't need to get married to do all the things that married people do. You can still share bank accounts, if you wish. You can still do all the same things and make even stronger vows to each other. The only real plus side to marrage is that it makes people swear to honor each other in front of an audience. Which even that when it really comes down to it doesn't mean much in the end.
If you look at history and the way things were done several hundred years ago. You will find that in smaller communities getting married was more about proclaiming that two people were a couple to the tribe/village and making it so everyone knew they were taken. It had a very different meaning back then and was done for very very practical reasons. Basically if a boy and a girl above a certain age starting hanging out alot together and showing affection to one another tribal leaders would take them aside and talk to them and then in some cases even force them to get married. In part because when they had children (since there was little in the way of contreception) the children would need a stable home just to survive the hardships of life. Today with our cities of 1000's it's not even possible to inform the general public of such a union. There is no way most people would even remember. It would be more productive to decide as a mutual decision to pay for an ad in the paper or online to let people know hands off.
It's just a tradition that people follow because it has been done for so long. We have given it a totally new meaning, but it doesn't really make a whole lot of sense for a great many reasons. The strange thing about tradition is often things had some practical reason at one point in time. People keep doing things far past that point and don't even remember how or why things were done in the first place.
History can be so awsome.
Edit: Don't get me wrong, I don't think its all bad. I just don't think it means what alot of people want to believe it means. Many people want to make marrage out to be some kind of ship like the titanic. Only the titanic wasn't unsinkable. It was just another ship just like all the rest of them. One might even say that the belief that it was unsinkable made it even more likely to be sunk, by ignoring the fact that traveling near ice flow's was dangerous to all ships.
It's sort of like you have two exactly identical houses. One house is just called a house. The other house has a grand opening when it's construction is finished. The only distinction between the two is that one of the houses had a grand opening. Besides that, nothing is really any different. How people chose to live in those houses will be completely independent of the fact that one house had a grand opening.
If the fear of divorce and the spliting of peoples assets is all that is keeping people together, as is often the case. Or the fear that people will be frowned upon by others around them. Or that their faith doesn't allow people to do what is best for them. It just doesn't make much sense to me.
