How you know you've had more than enough...

The living weren't meant to walk with the dead.
But the ghost came out from where I'd left him in my head.
Just like dust on a shelf, I just left him behind.
Months like years passing quicker as every moment went by.
I never let it get in me. I never even cried.
I just moved on through life as if he'd never died.
Cause he hadn't.
But I never knew and I never could see.
All the millions of places his heart now could be.
Although it wasn't my fault, or so I've been told,
I kept with me the guilt to grow with me and get old.
And sometimes I still wonder all of what could've been.
Would it have ended in more? Or just as a friend.
I'll look up to the sky and I'll remember your heart.
From the last time we talked to the beautiful start.
Not forgotten. Not at all. And he'll always be in my head.
But we're the living now, not meant to
be walking with the dead.
