First, am I going to having to do the Captcha thing everytime I post? I mean, I like it in theory but, in practice...a minor inconvenience...still, this site is better than other stuff so whatev...like paying taxes.
Anyways, the biggest thing to remember is to relax and enjoy it. Spend the date enjoying every moment, do NOT worry about every little thing. When you look back on this special day, you want to remember things like your first dance, not that the dj wore the wrong color tie.
P.S. keep in mind that her left hand will be on your right. I made that mistake during my first marriage...should've been a sign...she was in bed with other men within 6 months...oh yeah, back on topic...uh...
Also, even though you are married, you should still treat every day like it's your first date. Never take her for granted. I heard a story that really...hit me. This couple got married in their midtwenties and stayed together for many years when the woman fell deathly ill and had to stay in the hospital for months. As she laid on her deathbed, she awoke, looked over at her husband who had stayed by her side and said "You really do love me." and then she passed away. The moral, make sure your spouse knows that you love her everyday.
Oh: and a good wife always forgives her husband when she is wrong.
