I’ve never been big on reading poetry, but this piece by Mark Strand touched me:

In a field 
I am the absence of field. 
This is 
always the case. 
Wherever I am 
I am what is missing.

When I walk 
I part the air 
and always 
the air moves in 
to fill the spaces 
where my body’s been. 

We all have reasons 
for moving. 
I move 
to keep things whole.
