I actually wanna learn that too, but...never really get into it. ^^'
(Imagine I would get a young female japanese teacher lmao)
Its very hard, i just started and i have like 3-4 pages full of notes, such as the fact that the pitch of the word "hashi" changes the meaning from "chopstick" to "bridge" (HAshi = chopstick, haSHI = bridge)
lol
