Facebook can be used for many different purposes and people can interpret it many different ways. The electronic social media is second best to real, live contact and relationship.
I have Unfriended people that I am friendly with. I chose only to keep a small group of “friends” on my page because I want to simplify my life. When I had a girlfriend, I Unfriended her because she did not use FB. My kids Unfriended me because they did not bother with FB anymore or wanted my postings about them.
If you want to really connect and be in your friend’s life then text, phone, or better yet meet him. I think FB makes us lazy in actually connecting as people.
My two cents.
