But...

I am here, but the state isn't static.
I am everywhere, but no place in particular.
I am seen by all, but remembered by none.
I am conversed with by many, but understood by few.
I am conscious of everything, but make aware of it seldom.
I am what time forgot, but it won't forget forever.
I am one of few, but I got lonely so I left.
I am lacking something, but who will spot it.
I am the emotion, but for what does it bring.
I am thought of, but in what light.
I am the line, but white space precedes me.
I am that guy over there, but what was his name again.
I am not the same as them, but then how is the void filled.
I am quiet, but can the sounds of my thoughts be heard.
I am patient, but the virtue has overstayed its welcome.
I am a container, but lack the conventions that make me... me.
I am in flux, but this is not one of those times.
I am the source, but the cost is severe.

I am... but am I not?
