What about Facebook? I have reconnected with school friends. And their friends, and their friends... good for those of us who don't get out much. I mean, you still need to get out, but it's good late at night, or when you are lonely....
Sometimes I type a name into search and there they are after 55 years or more!
And sooner or later, you find out that some of them have the same problems as you. Pain and loss being biggies...
