Being a friend of the bride or groom's mom is usually the bottom rung of any guest list, second only to the obnoxious new spouse of a distant uncle. No one is wondering what you will be wearing, and no one will notice what you do wear.
Congratulations! You're engaged! Now enjoy this moment because it's the last time that your impending wedding will actually be yours. From the first phone call to the last, everybody you love will congratulate you while systematically working together to bring down the happiest day of your life.
Bad weather aside (because no one wants it to rain or snow on their wedding day), things happen. "Stuff" happens. Think of possible things that can happen and plan ahead for potential pitfalls or delays.
My husband swiped a finger across his eye. I knew better than to look at him. One glance and we'd both be bawling. He was not a crier; he could watch the Hallmark commercials on television and not even hiccup. But weddings were different. Weddings unnerved him.
