Just Die! rest of my life

I thought I'd know you for the rest of my life
but the world told a different story.
We were close, closer than brothers or blood
I thought we were inseparable.
But you were like the lunar phases
slowly moving, but always changing
I looked away for a fraction of a second
when I turned back the friend I knew was gone.
I turned my face away
YOU FADED, YOU FADED
I looked in a different direction
and our friendship turned to vapor.
Can't think about what was said that night
or hold on for the rest of my life
because you never know when the sun will go down on you.
