I am not trying to paint a dark picture bit remind that when the going is good it is wise not to let down your guard.
Consciousness demands ever vigilence.
I remember back in 1980 when my son Gregory graduated from Antioch in Yellow Springs, Ohio. It was a beautiful sunny day and the commencment was held on the campus lawn. All proceeded as you discribed above. But one by one the speakers took to the podium, among whom was the widow of the Rev. Martin Luther King, and all said the most glorius things to the the graduating class and their parents. I was in a good mood until then, dressed as I was in my brown and white pumps, seersucker suit and panama hat, and began to wonder the pollyanna being thrown at these kids.
