Famous quotes containing the word doors:
“He took the props down used for propping open,
And set them up again for propping shut,
The widespread double doors two stories high.
The advantage-disadvantage of these doors
Was that tramp taking sanctuary there
Must leave them unlocked to betray his presence.”
—Robert Frost (1874–1963)
