Would I could answer
This comfort with the like! But I have words
That would be howl’d out in the desert air,
Where hearing should not latch them.
– William Shakespeare
Macbeth, Act 4, Scene 3. Ross is understandibly hesitant to give Macduff the dreadful news about the murder of his family. He has words that should be howled out into the desert air where nobody could hear them, he says.
