Good for you, Mary Dias. Yes, as you said, their loss. I have a sister in Hawaii that I have been out of touch with for about 40 years, and we have since become good friends on FB. She was adopted by my dad & step-mom after my parents divorced when I was 9. In 2016, I spent a week with her at her home on Oahu, and we did lots of hiking and other adventures together. That would never have happened without FB. Also, a childhood friend, that I hadn’t seen in almost 60 years, found me on FB, and we have rekindled our friendship.
