First of all, turino, it's "LAOWEI"...bushi LOUWEI. Get the basics right.
Secondly, Kevin has found himself a job he likes, in a city he likes, at a salary he likes even more. What's wrong with that? Isn't that what every FT is looking for? There are conditions and demands in every contract that can be negotiated away or ignored.
Other teachers at that school are either happy or not. Everybody is different!
Just to keep the record straight, I know Kevin. I have met him. I don't like him. I wouldn't even contemplate joining the same school, and have him as a colleague. That said, he has found himself his dream job. Good luck to him. Doesn't mean that it's every ones' dream job.
