When you get married, you get another set of eyes. If you aren't careful, this other set of eyes that sees the world differently can become a constant source of tension and conflict -- with each of you endlessly trying to get the other to see everything like you do and win them over to your view. You can let your different ways of seeing give you a broader, wider, fuller view of the world. Instead of seeing with two eyes, you're now seeing with four.
