The phone I got when I started my current employment has a recycled number, which apparently used to belong to a door salesman (not a door-to-door seller, but someone who sells doors) in the other end of the country. Not everybody in his extensive network had gotten the message that he no longer had this number, so I got calls and messages intended for him for quite some time.
This was an interesting phenomenon as only a certain subset of his acquaintances had failed to update their phonebooks and this subset of course shrank over time, as they called me and got informed. So, I would get sort of an attenuating sampling of his life as reflected in his messages, I could detect when his first daughter was born, when distant relatives remembered him for Christmas, and so on.
I haven't received such calls for a long time now, but suddenly this last week there have been several, apparently from people just tenuously related to him, but who still have been spurred into calling. I hope this is just a statistical fluke, rather than something serious having happened to him.
