Yes or No?

You are planning to marry the best guy in the world. You've got the ring to prove it, too. He's nice like Clark Kent kind of nice. You get along with all of his friends and family. Even his grandmother loves you. Everything just seems to be peachy, but suddenly, he pops the question: will you please sign the pre-nup? An article from money magazine made me think twice about this. Although for me, it's too late already 'cuz I've been hitched.
