Henry David Thoreau,
Walden — Chapter VI: Visitors
(1893)
“ Individuals, like nations, must have suitable broad and natural boundaries, even a considerable neutral ground, between them. I have found it a singular luxury to talk across the pond to a companion on the opposite side. In my house we were so near that we could not begin to hear -- we could not speak low enough to be heard; as when you throw two stones into calm water so near that they break each other's undulations. If we are merely loquacious and loud talkers, then we can afford to stand very near together, cheek by jowl, and feel each other's breath ”
