“It is curious to look back over life, over all the varying incidents and scenes - such a multitude of odds and ends. Out of them all what has mattered? What lies behind the selection that memory has made? What makes us choose the things that we have remembered? It is as though one went to a great trunk full of junk in an attic and plunged one's hands into it and said, 'I will have this - and this - and this.”
