Walls are interesting things. Sometimes they seem to come from nowhere. They block people physically, socially, politically, financially, emotionally and in so many other ways. They keep some people in and other people out. Walls are meant to get in the way. Many walls may seem be bad news at first but I've found they can also lead to interesting opportunities that may not have been seen if the wall didn't make me stop and turn around. Walls can also be decorated and hold art. Walls themselves can be art. They can hold treasures and provide protection. Walls have been around a long time, but have changed relatively little. Walls are interesting.
