As a person with severe social anxiety, I felt truly anonymous in my visit to San Francisco last summer. I was not worried or threatened like my wife. I knew all things come and go in SF. The inherent risks of SF seemed easier to evaluate due to the larger population. To me, it was bliss. The divide between rich and poor was no different than anywhere I have visited in the USA. A visit to Mississippi can open eyes to the evil dividing lines of human behaviors.
