I'm sorry, but I am one of those. I am the 'grey man' here, I hope I am unnoticed, unheard, unseen, uncritical in the face of Thai authority, unquestioning and uncomplaining in their sight. This is totally against my normal character and It took me 3 years of living here to understand how it works here and to adopt that persona and it serves me very well. I recommend it to others, especially to those who lose their cool in Immigration, DLT or the Land Office. There seems to be a lot of those people around.
