I'm ashamed to admit I don't know any other languages beyond English. I don't know how to speak Gaelic either - believe it or not, its not taught in schools generally here in Scotland, at least not in the central belt. Mainly its just the north west coats and north Western Isles (Outer Hebrides) that speak it fluently. You'll need to ask your Dad what the name of the village was for me :-)
I've heard Korean, as well as Japanese and Chinese are quite challenging. Are you at the point where you can have a basic conversation yet or still starting out?
