So among common normal Issan folks I don't think you have a problem acknowledging a question or agreeing to something with that sound. IMO. but everything in it's right place and time.
My GF is northern and I was surprised how deep the resentment actually is towards anything Issan, and totally unfounded as far as i can see, just traditional deep Thai regional class divides.
