Bright, FB is a social medium that a lot of people are using now. Whether what they post is the truth or not, time will tell. I call it the place of "bragging" for many who really want people to think that they are happy and doing a lot of cool things in their lives.
I wouldn't be too concerned about him using it. The desire to post will eventually die down, but right now, it's the coolest thing since the two dollar bill. As for the people posting there, at least it's people he knows.
Just because your son isn't invited to join isn't something I would be too concerned about. If you son wants to be part of his circle, he could send him a request...but otherwise, I wouldn't let on that you or son (might) know about it. As for looking at it, well, that's your call, but I can tell it disturbs you.
No 2x4's from me, but I will only say this, if things continue to perturb you, then stop them. The more time you allow things that perturb you to continue, the more your anger will fester. Your health and well being are far more important than things like this.
Try to keep the focus on you and your life. What he's doing...well, let's face it...he's trying to relive his life as a 20 yr. old and we all know that you can't go back, only forward.
Take care.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
