I have sent an email to my dad basically forgiving him for what happened growing up. I have posted the note in my Vox blog as a Friends and Family posting. I may at some point in the future make that posting public, but I haven't decided yet. I certainly wanted to keep a copy of it. I am very proud of what I wrote. I'm sure it's not perfect, but I believe it said what I needed to say.
I feel I can move on now--with him or without him. There will be questions unanswered either way, but I have said my peace. At the very least I can go to bed because it's late. :)
