You might want to call up somebody you haven't seen in a while. And if the yearning to connect with someone from your distant past comes over you, heck, you should do just that! Look them up and say hello. Maybe they've got something (a memory, an insight) that you've been missing. Maybe you'll both just be glad to see that, yes, things change and people lose contact, but there's still some core self that remains the same and still appreciates the connection it once had with a kindred core self.
