Empty Spaces

I just realized that some times, in the cases of some people in our lives; just knowing that they are there is enough.
Today, I found out that somebody like that, from a long time ago isn't there any more. Not on my friend list. I don't know when the unfriend-ing happened... and more scarily, why.
A part of me is telling me to continue to live in blissful ignorance
While another part is screaming out one of the obvious possibilities.

Empty spaces.... They don't seem to be getting filled
I just seem to collect those as a hobby.

Wondering and wondering and wondering and wondering.....
You know what.

You know who.
