Thinking about a conversation I was having with an acquaintance years ago. He was a friend of a friend and we were talking about food. I forget the exact phrasing but I brought up loving avocados. He said “what’s that?” I was a bit surprised and explained. He responded “OH thats crazy I thought that was one of those made up words”. The statement was like a flashbang I had to contemplate for a few minutes. PERSONAL STORIES ONLY, DO NOT INCLUDE A STATEMENT FROM A CELEBRITY OR POLITICIAN.
There’s also chess960, where the positions of the pieces are randomized (with constraints). I like it because it removes memorization of positions as a factor.
