Herbert Dainer knows the world is ending tomorrow.
I mean the guy isn't crazy. He's gone through life up to this point feeling sad for all those who prophesied about the apocalypse - feeling sad in a kind of superior way, but feeling sad none-the-less, I think. Regardless, though, the point stands: Herb knows the world will end tomorrow. He doesn't know how and he doesn't know why, but he knows. He knows for sure.
And what do you do about that? Knowing he's surrounded by reasonable and scientific people, what do you do? How do you make your son stay home from his sleep-over so you can spend the last hours you have as a family? How do you get your wife to come home early from a business trip?
Herbert takes a drive and thinks it over.
