We urge one another to take it easy. I give them five bucks.

A block down the street I meet a vigorous workman who is wheeling along some kind of industrial trolley; it has what appears to be a tank of propane on it.

We make eye contact. We nod politely. I walk past him. "Hey! Excuse me sir!" he says.

"Yes?" I say, stopping and turning.

"Have you seen," the guy says rapidly, "a black guy, about 6'7", scars on both his cheeks like this—" he gestures—"wears a black baseball cap on backwards, wandering around here anyplace?"

"Sounds like I don't much WANT to meet him," I say.

"He took my wallet," says my new acquaintance. "Took it this morning. Y'know, some people would be SCARED of a guy like that. But I'm not scared. I'm from Chicago. I'm gonna hunt him down. We do things like that in Chicago."

"Yeah?"

"I went to the cops and now he's got an APB out on his ass," he says with satisfaction. "You run into him, you let me know."

"Okay," I say. "What is your name, sir?"
