On Saturday’s language lesson, the instructor was explaining to me that “Kha” at the end of the sentence primarily is to make the speaking polite.
So, in theory, I can politely say something like:
You f-ing s-hole, khaaa. (insert wide Thai smile here)
I think. I’ll have to ask in my next class. Because I’ll bet my next 40Baht meal that that’s what a lot of Thais are saying to our farang backs. And perhaps wheedle K. Ake to start teaching me cuss words. That is when you know you’re truly learning a language.
