I'm an extrovert. In my youth, I tended to remember personal details about people without trying. This went really weird places at times. People thought I was deeply interested in them because I happened to remember them. My best guess: humans are designed for a little village or tribe of around 150 people and we really aren't that good at navigating social anything outside that circumstance. Edit: I say that in part because I have read that Napoleon remembered personal details like that and it's part of why his troops were insanely loyal and would literally die for the man. I've read he liberally abused their assumption that he must deeply care because he could remember stuff about them. Some people just remember such things without trying. It's other people who decide it means x, y or z when it doesn't.
