What image(s) come to mind when you read this poem?

“there is a place in the heart that
will never be filled

a space

and even during the
best moments
and
the greatest times
times

we will know it

we will know it
more than
ever

there is a place in the heart that
will never be filled
and

we will wait
and
wait

in that space.”

― Charles Bukowski

I know that a heart is obvious but I’m looking for something different. Please use your wonderfully creative minds and help me out.
