Your leaders signed the metric treaty at the same time mine (Swedish) did, hundred some years ago. We changed right away you didn't.
I'm glad we did. Before we whent metric we had two different inches and a ton of strange measures.
We will not have to learn French, those days are long gone. Now English is the lingua franca of the world. What will the next be? Chinese? Almost a third of the worlds pop speaks it already. It's like the old Monty Python song says :-)
(I can't use the smileys, strange) This is all said on a humourus note I'm not arguing.
