“And his wish is intimacy,
Intimater intimacy,
And a stricter privacy;
The impossible shall yet be done,
And, being two, shall still be one.
As the wave breaks to foam on shelves,
Then runs into a wave again,
So lovers melt their sundered selves,
Yet melted would be twain.”
—Ralph Waldo Emerson (1803–1882)
“Time for the flat-headed man. I recognize that listener,
Him with the platitudes and rubber doughnuts,
Melting at the knees, a varicose horror.
Hello, hello. My nerves knew you, dear boy.
Have you come to unhinge my shadow?”
—Theodore Roethke (1908–1963)
