“He said “Next time can I bring my friend?”
And I thought “Does he mean friend?”
And I thought “Yes he does mean friend.”
Which was quite bold in those days.
It was the Dark Ages. Men and men.
And they could still put you in prison for it.
And did, dear.”
—Alan Bennett (b. 1934)
“The lies fall like flaxen threads from the skies
All over America, and the fact that some of them are true of course
Doesn’t so much not matter as serve to justify
The whole mad organizing force under the billows of correct delight.”
—John Ashbery (b. 1927)
