" In general, one's memories of any period must necessarily weaken as one moves away from it. One is constantly learning new facts, and old ones have to drop out to make way for them. At twenty I could have written the history of my schooldays with an accuracy which would be quite impossible now. But it can also happen that one's memories grow sharper after a long lapse of time, because one is looking at the past with fresh eyes and can isolate and, as it were, notice facts which previously existed undifferentiated among a mass of others.
