Nick, writing a book often means that the writer has to "commercialize" its content, but posting on forums like this one means the teacher can freely say what he wants to say. However, we do have some transvestite teachers on, don't we? Asia, for western countries' teachers, is a really tough place to work in education and there are a few other fields of business foreigners have great troubles with there. Polarizing issues of the real experiences does not serve the interested ones, does it?
Cheers and beers to commerializing the cut throat business in Asia :)
