Famous quotes containing the word door:
“The door is opening. A man you have never seen enters the room.
He tells you that it is time to go, but that you may stay,
If you wish. You reply that it is one and the same to you.
It was only later, after the house had materialized elsewhere,
That you remembered you forgot to ask him what form the change would take.”
—John Ashbery (b. 1927)
