“What does nostalgia mean to a child? An abstraction. A standing stone waiting for them in the mist. Walk a path across some decades, any path you like, and the word will gather weight. It will come to you trailing maybes and might-have-beens. Nostalgia is a drug, a knife. Against young skin it carries a dull edge, but time will teach you that nostalgia cuts - and that it's a blade that we cannot keep from applying to our own flesh.”
