kate,
If more people had your sound reasoning, and forgiving heart, their lives would be so much better. You've found a place inside where you can put everything into perspective and see it for what it is, and still love. That's very rare. I know others reading your post will be inspired by it, just as I was. You are not only handling your personal grief, but you are making room at the same time to allow your Mom to just be the person she is...and doing so with love. You are amazing. I know your Daddy is looking down on your with a proud heart.
