Writing: Technical Rhetoric

a quote of wisdom. from a random homeless man I saw today, walking through Lincoln Park, he was grumbling this rather loudly @ 10:15 AM, as I sat outside a popular coffee shop:
"Shit..Assholes,the shit comes out their assholes, the shit comes outta their assholes!!, Assholes...(grumble, grumble outta sight)" The wonderful ambient Chicago sounds, provided so graciously from one vagrant to another, I would have given him half of my muffin, but he shuffled by too late... and I didn't catch his name.
