I was down there visiting him just last weekend, for which I'm very grateful. He was fully lucid and happy to see me (though extremely weak).
He was a good man, and a good dad, and I'll miss him very much.
I may have more to say after I've processed more.
(And I'm glad now I tried to sell my Worldcon membership, or I wouldn't have posted to this journal since my grandfather died eight years ago. I need to post more, or indeed at all.)
