Anthony, my condolences. These loses are immense and take time. For what seems like a long time, the absence is vast. Then remarkably, after settling into their new place in the universe and your memory, the deceased come back to mind, big time. Your dad had a lot to teach you all the way through the end. And he has a lot to teach you in the future, the questions you asked and the questions you didn't, a connection to your ancestry in generations going back. I remember losing my dad (and mother, and late wife), each minute, in detail.
