Which set of lines in this excerpt from "Easter, 1916" by W. B. Yeats suggests that the speaker had only a limited acquaintance with the people he is writing about?
1.) I have passed with a nod of the head
Or polite meaningless words,
Or have lingered awhile and said
Polite meaningless words,
2.) Being certain that they and I
But lived where motley is worn:
3.) All changed, changed utterly:
A terrible beauty is born.
4.) Hearts with one purpose alone
Through summer and winter seem
Enchanted to a stone
To trouble the living stream.
