When I was 6, I was once deeply gutted by the realization that I'd never know the inner life of a class bully. This was a core theory-of-mind moment, when it dawned on me that I'd *never* be able to see the world the way anyone else saw it.
Oh, later on I'd sometimes try to "be understood", as silly humans do--but I'd always come back to that early lesson, that we all live with "self-evident" truths others can never know as we know them.
Good lesson, if tough.
So thank you Robert--ya stinker!
@MLClark Don't remember much about it. π
