I am changing phone numbers so this seems like an opportune time to go through all my contacts. I have lots of contacts from when I worked at various places that are no longer in business. I have lots of contacts from long ago places I lived. I have lots of contacts from places I visited and planned to visit again.
Now seems like a good time to clear them out and streamline. I am moving the keepers over to my new phone. I plan to export the others and archive them before I turn off the old phone. This brings back lots of memories of places I was, and people I knew.
