Come and Gone

It is fascinating that people constantly flicker in and out of my life. It is difficult to keep track of them. I'll have old friends I'll get back into contact with whom soon disappear. Are all relationships based on proximity? I'm just as guilty, as I remember losing track of my best friend when I moved to CT. We are back in touch, of course, but with others I am not as fortunate. What bothers me most are the ones who claim loyalty and still vanish off my radar. Despite efforts, even the ones I care about most are lost.
