Does that mean that things are going / went bad for you in China.
Like you, I think that its wrong to bail on a school, but sometimes its the best of 2 bad options.
I had to bail on a school (not in China) at one point. I felt terrible, and frankly the bad situation was caused by my not doing the due diligence I would have done if it was a chinese employer. The day I arrived I realised that it was a big mistake, but I was so determined to be someone who kept his word, and to not run out on the school days before the start of semester leaving them with no possibility of getting a replacement teacher, that I decided to stay.
By the time I woke up on my third morning i knew i had to go, and although I felt incredibly guilty, there's not one doubt that I made the right decision. It would have been disasterous to stay.
I'm not ancient, but I'm old enough to know a bad situation when I encounter one, but if I'd been paying proper attention in my skype interview, i could have avoided some of the most stressful days of my life.
The thing is, it was basically my fault, but I came out of it having had an interesting and educational experience.
So I think midnight runs are wrong, but the very nature of throwing yourself into the unknown is that however careful you are, it's possible to eventually make a mistake.
As I say this wasn't china, and I'm not sure there's a particular problem with China, but the cultural differences can really accentuate misunderstanding.
