Oxygen

as we grow older
the world becomes stranger
this is where I begin
if I could figure
why I'm big sinner
why I waste my time
in between sentences
that's where I've lost my mind
I can see the cycle
in a half circle coffee stain
there's rust in my brain
that's mostly the oxygen
counting the ways that somehow
don't matter at all
this is where I end
in the middle of nowhere
it's only small comfort
for those in my wake
this is where I end
