When I realized that all the crazy thoughts I had as a child were all
true, I was driving in my car.  It was about 3 years ago.  Nothing really
happened to trigger it.  I was just leaving my office when it suddenly
hit me. I started laughing, like really laughing - hard, and crying - 
really crying hard at the same time.  I should have pulled over.  It was 
the most tremendous sense of gratitude I ever experienced.
