Nor are the memories we all have of one another, even in love, the same. I had known Albertine recall in extraordinary detail some remark I had made to her at one of our first meetings, and which I had completely forgotten. Yet of another incident, permanently settled deep in my mind like a pebble, she would have no memory at all. Our parallel lives seemed like those garden walks where, at regularly positioned intervals, tubs of flowers are placed symmetrically but never opposite each other.
