Sometimes, Facebook is useful.
I ran across a reference to someone I knew and worked with thirty years ago, with a link to her Facebook profile. When she moved away to another part of the state way back when, I helped her move and get settled in. She had her issues, but was basically a sweet person. After she moved, we lost touch.
So I clicked the link to see whatever happened to her and what she was up to, and found out she turned into a Bible-thumping right-winger. Yikes. Clicked out of there, grateful to have lost touch.
