What is the real beauty of being married or living with someone?

Its early morning and you both wake up at the same time. You turn over for a morning kiss and your breath “ain’t makin’ it”. Do you hold your breath and carry on or do you call time out and head for the mouthwash? She sees you have not shaved in three days and her hair looks like a tornado just left it. You both have “bedhead”. Question: after being in a relationship or marriage for such a long time, do you and your partner just accept these downfalls? Is this the real beauty of a partnership?
