Tragedy of the commons and the uncommons

For any econs people reading this, please be rest assured that this entry has nothing got to do with what you all thought.

It seems like when couples start dating, they see more commons than uncommons. ( or they choose to see more commons )

Ironically, its until they get married where more "emphasis" is placed on the uncommons. And what that was seem common becomes more and more uncommon.

Is there such thing as a contract marriage anyway? And yeah, I do not mind a contractual gf for the moment. =p
