"Human memory is a strange thing," he observed. "How it comes and goes. How sometimes folk tuck the past away so deep they forget it's there at all. The human mind is full of byways, dead ends, locked chambers. Strongboxes guarding matters too painful to be brought into the light; dusty corners where items considered too trivial are tossed away. You'll remember one day. And if you do not, perhaps it is no matter."
