My mother is the worst person to give directions to. It is guaranteed that she will get lost. It does not matter how clear you try to make things. She will not remember anything you say, and even if you write it down it will not make sense to her. I told her about real time gps vehicle tracking systems. They can tell her, out loud, where it is that she needs to go. If she veers off track, it will let her know. She could never get lost as long as she had a gps system to tell her what to do.
