Preparation isn't possible

As I watched my oldest daughter Hannah take part in the graduation ceremony processional at the University of Alabama - Tuscaloosa last Saturday, I was really really happy and proud. Watching her finish the process she started so long ago, I was excited about her future for her as any parent would be. We had spent the previous couple days watching and learning about her life in Tuscaloosa, showing her off a bit to her grandfather and aunts. Her uncle Hector and his daughters made the 600 mile drive to Alabama Friday to watch the ceremony Saturday morning and then drive back!!
Seeing her apartment, her work and the respect she has earned from her coworkers, and spending time with her, I realized I was watching an adult live life. That was very cool to note.
But sometime in the middle of the ceremony, I welled up. I'm not sure where the tears originated or the feelings behind them even now. I KNOW how proud of her I am. And how I feel like her mom and I did the best we could and it shows. But in some ways it is like the end of something irreplaceable. I wasn't ready for that.
Happy and sad. Sweet and sour. Life is wonderful and I love all its tastes!
