caress a stranger’s flesh with lucid oil before
a word is spoken
no feasting
before a tale is told, before
the stranger tells his name.”

“I spent my life mixin’ with your breed, and I don’t like it. Get me. You can hide behind a lot of red tape, crooked lawyers and politicians with the gimmes, writs of habeas corpus, witnesses that don’t remember overnight, but we’ll get through to you, just like we got all the rest.”
—Ben Hecht (1893–1964)
