While these traditions are important to know (lowering your head, ¾Õè ¹éͧ, ¡Ô¹¢éÒÇËÃ×ÍÂѧ ) I think it is important to point out that these are traditions from all regions of Thailand, not just Isaan. I think it might be worthwhile to have a thread on the differences between village life and city life....or a thread on Thai culture/politeness.
