Tim, I've been married 31 years ( I was just a babe from my mother's arms when we wed!) and you have topped anything I've ever encountered in my relationship. The best I can come up with is shortly after the birth of our son (who is now 21) when we celebrated our anniversary. I was nursing this child and could not leave him behind for very long. He thought bottle nipples were poison!
In any case, the anniversary dinner I remember most is this one............we ordered pizza and sat at the coffee table (by candlelight) and ate the pizza from the box. We laughed and had a great time. My son looked up from his dinner with a BIG smile and love all over his face. It was a great night and we weren't even on a cruise.
If you are going to walk on thin ice, you may as well dance!
