Thailand is a high-context and collectivism culture so Thais often avoid about the conflict with others, they would like to show and pretend a respect, Thais effectively are able to their control emotion, modest and politeness and know the appropriate pronoun to greet other. For example if I meet the leader who are older than me, I will say “khun are… or thun” (
叔叔先生。。。or 先生).
