Graffiti in Sonnets- Reading

Two men playing chess on milkcrates in an alleyway.
At first glance they're thugs, no goods, degenerates;
Look again, they're scholars, poets, graffiti in sonnets.
Breeze kicks up.

Keep walking on, Sister Mercy. Keep walking on.

There's pride here, you can smell it,
like fresh ocean salty swell, it
fills the air. It holds you.
Leaves pin-drop.

Keep walking on, Sister Mercy. Keep walking on.
