Famous quotes containing the words thread and/or form:
“We construct a narrative for ourselves, and thats the thread that we follow from one day to the next. People who disintegrate as personalities are the ones who lose that thread.”
—Paul Auster (b. 1947)
“While they stand at home at the door he is dead already,
The only son is dead.
But the mother needs to be better,
She with thin form presently drest in black,
By day her meals untouchd, then at night fitfully sleeping, often waking,
In the midnight waking, weeping, longing with one deep longing,
O that she might withdraw unnoticed, silent from life escape and
withdraw,
To follow, to seek, to be with her dear dead son.”
—Walt Whitman (18191892)
