during confirmation, they told me it was one of the sacraments like baptism. you have to do it. not everyone is religious.
people have gotten married to have sex. well, sex has become very casual so...and having a kid together is never a reason. never a good one at least.
another reason i could think of is for financial reasons. not everyone is a gold digger and not everyone has gold to dig for. also, there are those who have gain financial security without another person.
so why does the rest of the world get married? and the decision to get married for the aforementioned probably was not originally or admittedly based on those reasons so what is it? US citizenship? what are the benefits?
