Wislawa Szymborska from "View with a Grain of Sand"

We call it a grain of sand,
but it calls itself neither grain nor
   sand.
It does just fine without a name,
whether general, particular,
permanent, passing,
incorrect, or apt.

Our glance, our touch mean
   nothing to it.
It doesn't feel itself  
   touched.
And that it fell on the windowsill
is only our experience, not its.
For it, it is no different from
   falling on anything else
with no assurance that it has
   finished falling
or that it is falling still.
