I am sorry to hear about your loss. Please accept my condolescences.

I'm mentally preparing for the fact that within a few years (5 - 15? Who knows) I shall be fatherless, too. He's still going strong, but getting closer to his limit.

When my grandparents had died, my father said there was something really weird and wicked about suddenly becoming the oldest generation in the family. Not being a man of many words he didn't elaborate, but I think I can guess what he meant. In a few years I shall have to deal with it, too. I can't say I look forward to it - but it is how things are.
