Facebook is a funny thing. I remember signing up back in 2004 at Penn State. There was no news feed, no wall, no drama. You could poke people and that was pretty much it. These days, Facebook is essentially a diary and you just don’t want anyone reading your deepest thoughts. Only let people that you respect join the circle. Do not prematurely friend or accept a friendship early on in the relationship. I would say you can friend after five, pleasant, in-person interactions because the last thing you want to do is un-friend, but sometimes it must be done. Parting ways on Facebook is just like drifting apart in real life. It happens. Why hold on to something/someone online when there’s nothing there in reality. It just doesn’t make sense. So if you ever happen to be the victim of an un-friend, it’s OK. Life goes on.
