“A man was to live in that egg-shell day and night, a mile from the shore.... Think of making your bed thus in the crest of a breaker! To have the waves, like a pack of hungry wolves, eying you always, night and day, and from time to time making a spring at you, almost sure to have you at last.”
—Henry David Thoreau (1817–1862)
“We are finding out that what looked like a neglected house a year ago is in fact a ruin.”
—Václav Havel (b. 1936)
