I'm sorry for your loss, but I know how you feel. I just lost my grandmother back in April, and for me, it wasn't the loss that hurt me. It was the fact that she lived right next door, and I could have gone and seen her every day but I always put it off til "tomorrow". Well, April 3rd, tomorrow never came for her, and I never got to say goodbye, or tell her that I love her before she passed because it just happened so suddenly. She was fine one day, then sick the next, and gone. So I'm stuck with all sorts of regrets. I'm glad you at least got to spend time with your Pop before he passed, and again, I'm sorry for your loss. I hope things are well for you and yours.
