"At every party there are two kinds of people: those who want to go home and those who don’t. The trouble is, they are usually married to each other."
Marriage is the biggest gamble of world. Sometimes you win but most of the time you lose. So Author has mentioned the funny thing about marriage is that you get stuck with opposite nature. If you love parties then you gonna engage with the person who hates going out. So there are lots of things on which you have to compromise. I hope someday, someone will break the bad image of marriage and comes out as a happy married man/woman. Well, impossible!
