I feel we're riding a knife's edge and there's a hurricane brewing in the gulf of absurdity.

Incidentally, I feel like this is why it is so hard to actually learn from history. You can read about the 1918 'Spanish' Flu, but you think "we're smarter now". etc.
Also, if your grandpa likes telling war stories, it's only because he survived.
As someone whose parents, grandparents, and entire family lived in Italy through WWII (and one grandfather who lost an eye in WWI), nobody liked talking about it.
If they did talk about it, it was usually brief and imbued with a feeling of "thank God it's over. what a tragedy that we were all used as pawns by the political class for nothing more than selfish ambitions."
