I thought her behind my back,
Yea, her I long had learned to lack,
And I said: ‘I am sure you are standing behind me,
Though how do you get into this old track?’
And there was no sound but the fall of a leaf
As a sad response; and to keep down grief
I would not turn my head to discover
That there was nothing in my belief.
–Thomas Hardy (The Shadow on the Stone)
