Shape Rule
(lemmy.blahaj.zone)
[A person offering a second person a Klein bottle. The second person rejects the Klein bottle. They have a plate of regular three dimensional shapes in front of them. They have picked up a rectangular prism on their fork. In the upper left corner is the text: "No! A responsible adult says no to non-orientable shapes"]
He is offered an interesting shape, but he is not so in-kleined.
I'd appreciate an outside perspective.
