Ghost or a Stranger?

Are you...

Its been a long time,
How have you been?
When was the last time we spoke?
Too long. I cannot remember.
Me? I've been okay.

Hey,
Its been quite a while.
We don't talk anymore.
Oh, yeah, I'm sorry for not answering you those last times.
Going through things, you know?
Yeah, I guess you don't.

Hello,
Just wanted to see how you're doing.
Been a year.
Hope everything is okay.
I'm not doing that great.
Hello?

Hi.
We see each other now and then.
You don't recognize me, but I recognize you.
Your eyes go right through me, foggy and distant,
How did this happen?
