Have you ever had a phone number that was similar to a well-used one and you got a lot of wrong numbers?
We've had the same number for over 30 years and I don't want to change it. However, it's almost the same number as that of a barber shop (we get, "can you help me with my dreads?") and a psychologist (usually what happens: a third party calls and leaves personal information about a second party on our answering machine.)
When I was at Auburn, there was a very desirable corner room on the sorority floor. However, you took it knowing that the phone was one digit away from Auburn's city weather line. No one ever lived there more than one term.
Frustration.
