Dennis wrote a column addressing this topic in marriage years ago and to this day is still attacked for it. The left's basic argument boils down to "there are no 'shoulds' in life." In reality, we are all governed by "shoulds," even in marital relationships. If this concept offends you, think about what you do if you're not in the mood to go to work. In general, a fleeting "mood" should not be the determinant factor of your actions.
