Facebook friends

As I scroll through the list of friends in my facebook account, there is a button that assist me to classify my facebook friends as either close or acquaintances. A thought came to mind, should there not be a category for in-process-to-be-close or in-process-to-be-acquaintance. After all, through time and interactions, friends will either drift apart or become closer, so there should be a in-between category. Most of my facebook friends are on the island and I am so far away. I guess it's more of reconnecting with some of my facebook friends that I have been close to before, meeting up with some of them personally when I am back there.  I should be forward looking, maybe I should be making some facebook friends over my part of the world.
