Silly little Atoms

It's hard to be reminded
of what I never knew
but always felt;

basic chemistry tells me
that I am mostly dead space.
We are filled
and we are suckers,
for the atoms within our star dust(
seething pockets of blood,)
are nothing
but walled courtyards
containing a single marble

which is loose
and knocking on the neighbors door,
asking for more room.
