I found this fascinating quote today:
The other key is to not have "daydream expectations"- that man you are marrying is the same man that you have spent many a day with, the same man who belches, scratches his butt, and unbuttons his pants after he eats the buffet at Ponderosa. Don't dream that once you walk down the aisle he is going to suddenly grow a mass of golden hair, increase muscle mass by 25% and suddenly send you flowers on a weekly basis. If he hasn't done that yet, he is not going to do that then. Finally, have your eyes open when you walk down the aisle. Any habits, uncertainties, or qualms you witnessed last week are still going to exist after the honeymoon. Marriage isn't going to stop infediility, lying, excessive spending, or any other habits you have been concerned about.Mommy Tyme, Mom Has a Voice, Nov 2009
