OK, Crankin, I read through your posts about both your "friend" and the FB settings. It seems to me that you're letting her dictate how you interact with your true friends on FB and that you let her under your skin.

Either learn to truly ignore her (easier said than done) or figure out the FB setting. I finally figured it out and it's lovely. No longer do I have to listen to this person's idiocy nor have to put up with him angling for another visit where we not only do all the cooking and dishwashing, but also entertain his girlfriend while he skis. Bliss!

Take control.
