I really believe that all of us have a lot of darkness in our souls. Anger rage fear sadness. I don't think that's only reserved for people who have horrible upbringings. I think it really exists and is part of the human condition. I think in the course of your life you figure out ways to deal with that.
The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter I should have advised him to continue the generation of the species by fashioning them out of clay.
