An older gentleman came into the library where I worked and asked for directions. He was trying to find his niece's place. From his vague description, I finally found it on a map, but when I tried to show him how to get there, his conversation kept wandering so much that I asked him if he had his son's phone number so that his son could help him get to his niece's place. The old man searched his pockets and came up with a piece of paper with his son's phone number, so I called it. The son was shocked that his dad, who has Alzheimers, actually was able to drive so far away by himself and had actually had the sense that librarians could help and had stopped at a library.
