Works very well ........... At least I know English.
I live in a middle class Thai gated village, all doctors, teachers, managers. All appear to be one months wage away from bankruptcy, new cars on minimum deposit, maximum repayment time. Borrow to send their kids to international schools. None know anything about the world outside Thailand.
My Thai cycling pal retired after 30 years teaching English in Thai highschool, but we have to talk in Thai as he can't speak one word of English.
