“While the Greek root of the word nostalgia, ‘nostos’, means ‘the return home’ — anyone who has been there knows that the return home is never without pain. Nostalgia feels like getting the blues. According to the Oxford English dictionary, ‘nostalgia’ is ‘a form of melancholia caused by prolonged absence from one’s home or country; severe homesickness’. Indeed, ‘Nostos might hold out the promise that, yes, you can return whence you came, but nostalgia happens because you can’t go home again.’”
— Carol Mavor, “A Bolt From the Blue”, Blue Mythologies
