Oh wow I was just posting my ponderings but thank you.
9/11 definitely cast a big shadow, and that along with Diana's death are the two events where I remember where I was when it happened. 9/11 was definitely a moment when the world changed, and I think Covid and now this will be another moment.
That's really interesting and now you say it, I suppose ww2 has been a big thing in my life just because I've heard the stories and seen some photos (my grandad liberated a concentration camp and we have some quite graphic photos), even had my grandads gun from the war at one point.
I suppose you can split it into what you lived through personally, and what cast a shadow and impacted your life in a wider sense.
