This is called "Strokes."
"Whether painter's sable or flogger's lash,
each slash is meant to stay, to mark the moment,
and to live on, bearing witness to all
who see the scar whether or not they understand where it
came from, brush or bullwhip.
Bubble or clot, hard block stopping blood to the brain,
blanks out territories that won't be heard from again,
blanks out the middle of a sentence,
the whole family of words, paints
over whole passages of a marked life, memorable to those marked
out, remarkable."
