*grin* The next time you forget it, I will be kinder and not remind you, good sir! Apologies for that!

I'm all down for your plan to linguistically spread "compersion" to the East of the Atlantic and "metamour" to the West of it. Only question is this: I'm in Japan right now, which is somewhat half the globe away from the Atlantic -- roughly equidistant via East or West. So, um, which do I spread? ;-D

(Actually, I think the answer would then be "both" -- particularly as neither term is in use here and polyamory is not really a known concept!)
