I have seen one person on Facebook with over 1500 friends. There is no way anyone could have that many friends and really know who each one was. LOL. It’s just a game to see how many people they can add. I know this person and I know for a fact that back in school days they also had to come in first, have the best of everything and be #1 in everything otherwise their mommy dearest threw a fit, so it doesn’t surprise me to see them competing for FB numbers. Many people will add people they don’t even know for this purpose. A friend of a friend of a friend, etc.
As for me, yes I have had 1 or 2 people to drop off my list. I have about 150 people currently on my list. I don’t even remember who they were now and it doesn’t really matter. All of them are people I have known or had an association with sometime in the past. If they want to come and go, fine with me. Not something I am going to get my BP up over. If I try to engage in conversation with someone on FB and they don’t want to talk back to me then I just don’t both with them anymore.
