Well, you know what they say, Pauldeane "there's nowt to fear but fear itself."
Four weeks in the classroom and you would have conquered your shyness. It'll bring the
best out of you, I'm sure. Just don't listen to too many disgruntles on the Internet
forums, that's all. Just ignore any mickey-taking and it'll go away. There will always
be disruptive influences in the classroom.

But its not just the classroom. Wherever you go you have to live with them in their society. Which is that is the hard part. Teaching yes is an adventure and a tough job but can be learned. Just read pauldeane. Google this phrase "the korean mentality" and read. Read what Korean people themselves have to say

I don't expect this young man to listen though. Before I went people told me the same and I didn't listen. Believe me however, I wish I had.
