Which set of lines in this excerpt from "easter, 1816" by w. b. yeats suggests that the speaker had only a limited acquaintance with the people he is writing about? i have met them at close of day coming with vivid faces from counter or desk among grey eighteenth-century houses. i have passed with a nod of the head or polite meaningless words, or have lingered awhile and said polite meaningless words, and thought before i had done of a mocking tale or a gibe to a companion around the fire at the club, being certain that they and i but lived where motley is worn: all changed, changed utterly: a terrible beauty is born. . hearts with one purpose alone through summer and winter seem enchanted to a stone to trouble the living stream.
