light is a bully
if you’re the wrong size
in the wrong place.
it will claw at your surface,
cracking and peeling
your very essence.
it will flip you around
and leave you spinning
until you break.
it will drag you
from a path you’ve followed
for millions upon millions of years
and beyond your control
send you to the heart of the sun
before blasting your ashes away
to the void of interstellar space.
light is a bully
but darkness a thief
that slowly takes and takes
until you equilibrate
with nothing left to give.
