This is the great boulevard. The main street, and a place of life. Here, of course, only the ghosts of life. But stay a while, and you might see them. The sounds of chatter from doorways, golden life spilling out, people in all of their noise and mess and dirt and love. Here they wear masks like animals, these ghosts who can not see you. Do you understand why?
You can talk to them, if you like. They never knew you in life. But preserved, here, their pattern can react to you as it would have done, just the same. You're in no real danger if you make anyone angry, although you might give yourself a fright.
