Marriage is difficult, perhaps the most difficult thing you can ever do, besides being a parent, but I think these two fine young people are up to the challenge. Here are two steady, responsible people who, I believe, understand the dire commitment they are about to make and will choose to keep that commitment. Because it turns out to be a choice, commitment-not some done deal. When you leave the alter tomorrow, there will still be a lifetime of choice and temptation and doubt and uncertainty in front of you. I didn't know that at my wedding. Getting married doesn't change you. Marriage changes you.
