They know that tragedy is not glamorous. They know it doesn't play out in life as it does on a stage or between the pages of a book. It is neither a punishment meted out nor a lesson conferred. Its horrors are not attributable to one single person. Tragedy is ugly and tangled, stupid and confusing.
Hollowness: that I understand. I'm starting to believe that there isn't anything you can do to fix it. That's what I've taken from the therapy sessions: the holes in your life are permanent. You have to grow around them, like tree roots around concrete; you mold yourself through the gaps
To forget is to blithely toss aside the hard lessons that were hard won by others before us, thereby needlessly dooming us to endure the hard lessons that are likely to be forgotten by those who will follow us. And it is altogether reasonable that in order to avoid this repetitive trouncing, God graciously granted us memories.
