okay, yeah, i get that -- no true universals; it's more like fractals, speaking metaphorically, where the closer you get, the fuzzier the edge gets and there's less and less way to tell where THERE starts and HERE ends... that's very clear and I've run into that before; probably even knew what to call it at one time! so thanks for that.

what about my shared meaning question? about that -- we just assume it works and lump along until we realize we're misunderstanding each other and call a time out to hash out a more precise blend of fuzziness? :).
