I dont think he thinks it's sacred. I think he feels it is secret and "exictingly dirty" and I believe his anger and condesceding comments are because he feels it in his gut that you "know" but your attitude startles him.

As for the rest happening in your life, I am happy for you. Next time you are in Maddison let me know. Maybe you can find the time to deliver something for me. K
