I love this quote and am so glad no one seems to know the exact wording or who wrote it, because I'm sure I never get it right. I believe it is not a quote about the rough men but us who can sleep peacefully in our beds at night without any clear knowledge of what is going on outside our wndow, our town, or our country. I thank those soldiers who fight on our behalf, and the police who protect us, but I think of the " rough men" as those we don't know about, doing things I don't understand, things I would never believe possible, with huge amounts of bravery that I know I could never have. The whole point of poetry is our own perception of it. But I also believe those who think we would live peacefully in our beds at night without these "rough men" are sadly deluded.
