From Antal Szerb’s Journey by Moonlight:
Past and present always played special games inside Mihály, lending each other colour and flavour. He loved to relocate himself in his past, at one precise point, and from that perspective re-assemble his present life: for example, “What would I have made of Florence if I had come here at sixteen?” and this reordering would always give the present moment a richer charge of feeling. But it could also be done the other way round, converting the present into a past: “What fine memories will I have, ten years from now, of once having been in Florence with Erzsi … what will such memories hold, what associations of feeling, which I cannot guess at at this moment?”
