Why?

Ok, I don't want to say that Koreans are lacking in common sense... but the evidence is mounting. Why do I come into school to find memos and other things on my desk that are in KOREAN? Do I read and understand Korean? Are they translated into English? No is the answer to both of these. Really, all I need is a co-teacher to fill me in on the important things from teacher meetings and schedule changes, that's all. Anyway, just wondering why they're wasting the paper on me.
