"The nameless, useless nobodies who sleep behind the taverns, who sleep beneath . Who sleep in burnt-out busses with the windows freshly curtained; in winterized chicken coops or patched-up truck bodies. The useless, helpless nobodies nobody knows: that go as the snow goes, where the wind blows, there and there and there, down any old cat-and-ashcan alley at all. There, unloved and lost forever, lost and unloved for keeps and a day, [...] there were they chop kindling for heat, cook over coal stoves, still burn kerosene for light, there where they sleep the all-night movies through and wait for rain or peace or snow: there, there beats Chicago's heart. / [...] For the masses who do the city's labor also keep the city's heart."
January 1, 1970
