That feeling

I hate that feeling when you notice that a friendship is slipping away...not necessarily ending, but becoming less important to one or both involved. If it's a mutual thing I guess it's ok, but when it's not mutual it's not a great feeling.
This happened to me with the girl who was my best friend through primary, intermediate and high school. She had things more important in her life than keeping up a friendship once we stopped seeing each other everyday. It sucks, I miss her heaps and constantly wonder what's happening in her life.

And now it seems to be happening again...deja vu...
