Albert Camus said this quote

Some, often without knowing it, suffered from being deprived of the company of friends and from their inability to get in touch with them through the usual channels of friendship, letters, trains, and boats. Others, fewer these, Tarrou may have been one of them, had desired reunion with something they couldn't have defined, but which seemed to them the only desirable thing on earth. For want of a better name, they sometimes called it peace.
