maybe it was something as simple as being talked to that way by a woman the salesgirl considered an `` uppity nigger '' ( again it was more his experience in movie theaters than any knowledge of history or even life on the streets as he had lived it that caused this thought , because this was like watching a movie either set or made in the '60s , something like that one with sidney steiger and rod poitier , in the heat of the night ) , but it could also be something even simpler : roland 's lady of the shadows was , black or white , one rude bitch .
