I just saw my oldest son off to college. We hugged at the airport. Upon releasing, he lingered on my face, his head tilted down from his 6'4" stature. The last time we held each other's gaze that long he was looking up from my arms as I nursed him. I think he was searching my face for tears, but I had none. That was uncharacteristic and I wonder where I will be and what I'll be doing when it hits me.
