I know for sure my old friend who I have not seen in some time is doing just fine.
What makes you think he's OK when you haven't seen him in all that time?
I only have check facebook once every couple of months to confirm this.
You can't believe everything you see on Facebook. Research shows that people grossly misrepresent themselves by posting only the most festive and happy photos and videos.  Anything hinting at negativity, even boredom, is omitted.
I think some of it is real, but Facebook is a stupid way to judge someone's life.
I am glad you understand that it is not good to judge people by what you see on Facebook. Not everything you see there is real.
