Sounds like FB works for you SGF, and I’m glad that it does, I also sincerely appreciate your attempt to educate me about its virtues.
I honestly can’t see any way that it could work to my advantage, if I need to contact friends/ family, I use email/WhatsApp.
My wife uses FB, but it seems to me that her nieces, great-nieces, and friends overload her with useless minutiae of their days.
One day she was upstairs, and the incoming message ding went on her phone, which was on the coffee table near me.
She called down, “Check that message out Jean, I’m waiting to hear from Zoë about meeting for a glass of wine.”
I picked up her phone, punched in her code numbers, and the screen was full of FB messages, e.g. “X is over the park with the kids”, “Y is at a PTA meeting at Kelly’s school”, “Z is on her way to the ante-natal clinic”, and on and on ad nauseam.
That would drive me nuts, but I guess that your friends don’t plague you like that.
