This morning. We knew it was coming, but it always sucks. He was much more of a grandfather than my real one ever was (who died probably 2 months ago now). And in the same respect, he was more of a father to my Dad than his real father ever was. Now all my Dad has left is his Mum, who isn't exactly in the best health either. Sad time, and I know my Dad is devastated. Just wish there was something I could do.
