It IS just you!
In dealing with the discussions and subjects that came up during his creation of "Stranger In A Strange Land", author Robert Heinlein grappled with some difficult and difficult-to-express ideas. For that alone, it's a good read. But not for that alone.
His idea is that whenever you encounter any other grokking thing — he didn't say 'grokking' at this stage — any other living thing, man, woman, or stray cat… you are simply encountering your 'other end'… and the universe is just a little thing we whipped up among us the other night for our entertainment and then agreed to forget the gag. He put it in a much more sugar-coated fashion, being extremely careful not to tread on competitors' toes.
