She wandered our neighborhood completely lost. As long as she had her dog, it would lead her home. As the dog became older, she left it at home and on each outing showed up at some door without reason. Invariably everyone helped her find her way home. He dog recently had to be put down, and for some reason her wanderings ranged further afield so that her family felt compelled to place her in a home.

To continue the story: About a year ago, Frau Beeli just walked away from the home. She was not confined, because she was not a threat to anyone. She was reported missing after about six hours and an intensive search began that evening. Despite the best efforts of the police and other authorities, she was never found. A year later we still think of her often. Her presence could be anywhere and so it is.
