Exactly, it's why I advise to push it into a Thai issue, we can never get anywhere.
I had a foreign teacher I was working with a couple of years ago. He was going out with an m5 student in another school. She just happened to be my wife's student. When I thought it was just dating, I talked to the teacher. It ended up that he told some lies about me. Ok.
Later, when he broke up with the girl because she wouldn't have sex with him and she was in tears. She showed my wife all of this pervert's sms and email messages. She was too scared to tell her parents because she thought she'd get into trouble and the teacher was blaming her.
So what to do? I talked him again and he proceeded to spread evil rumors about my wife around town. He claimed to be the victim (no, we aren't talking about Bruce here!) of such evilness. He claimed also that this girl, this m5 student, threw herself at him and he couldn't overcome her charms. Poor victim.
At this point, I went to our director since his actions were affecting the work environment and I thought a pedo shouldn't be working at the school. Well, she said that she already knew about the situation and she heard that the girl wasn't a good girl. End of discussion.
At the end of the year, I left and he stayed on for another year.
Interesting side note: He hires young girls to come in on the weekend to clean his home and do other things for him. Everyone in NST knows who I am talking about.
