Christine Lavin is singing a song about a 3 year old named Katie who says today is the best day of her life.I paused in my proofreading to wonder what was the best day of my life?I’ve had many great days, some ideal, but the single best day of my life? That’s a tough one. Obviously the list will include our wedding day and the days Kate and Robbie were born but the moments were great, the entire days, maybe not so much. After all, wedding jitters, rain, the entire delivery process…these are not what most people would think of as great ways to spend the hours. Sharing in the their triumphs, from plays to graduation ceremonies have also been highlights.A great day, to me, would be one that from beginning to end was filled with moments that brought pleasure and joy, where everything went as planned or if they were spontaneous, arrived in good ways. There was one day during the Christmas season about a decade back that I thought was the perfect holiday day and intended to jot down the events as a record of the day, but time passed, I never got to it and now I cannot recall what made the day ideal just that it happened.Great days have been doing things with the kids, such as the first day on one of our last family vacations, when these teenagers asked to go the Bronx Zoo then insisted on including a visit to the Children’s Zoo. There have been great days when it has just been me and Deb such as the time we took a day off mid-week and just drove north, meandering through small towns in Connecticut and Massachusetts just to see what we could find.During my professional career there have no doubt been really good days that were just mine. A surprise birthday party in my office, thrown by friends outside of DC, is certainly part of that list. Being able to sit and interview legends like Chuck Yeager or cute actresses certainly make for happy memories.But a single greatest day of my life? Boy, that’s a tough one. What about you?
