@eth, I really resonate when you say... "But these days I am reconciled with understanding that there are some things one will never know and that's ok." I think this kind of understanding has been incredibly helpful and only something I have found with getting older. Earlier in my life I think I was a lot more grasping of what I thought might be 'truth'. And yes, I think it is sometimes better not to remember some things, especially if they are going to bring again with them a lot of darkness to our present lives.
We often get deep, it seems to me!
