" Many years have passed since that night. The wall of the staircase, up which I had watched the light of his candle gradually climb, was long ago demolished. And in myself, too, many things have perished which, I imagined, would last for ever, and new structures have arisen, giving birth to new sorrows and new joys which in those days I could not have foreseen, just as now the old are difficult of comprehension. "

― Marcel Proust , In Search of Lost Time
