What helped me as a kid is imagine to write. That’s my left hand and than I know which is which without thinking too consciously (in case you’re right handed, it’s the other way around obviously).
But interesting that you know absolute directions easily. That’s a cultural thing actually. I think Australian Aborigines will say things like “my western foot hurts” because it’s more intuitive for them that way.
You got it all wrong, it’s their choice, too. That’s the whole point, it’s always their choice. It always has been. If you want to change that, you’re privileged. Their privilege is the status quo, the default, their god given right. God gave you nothing.
