Well, CL, I wouldn't post on this one, if you didn't. It's really hard to counter your highly professional post that most likely indicates the real truth behind the motives of a disgruntled foreign teacher. But I bet you have never felt such a pain. Darn, my grandma has told me not the say "never" ever. :)
Cheers and beers to all foreign teachers that have gone through any pains on the mainland
