Pragmatics in my everyday practice - Meeting and addressing people

This short piece of work would intend to show or present my everyday teaching practice from pragmatic points of view. I learned applied linguistics before, or at least my college professors gave it a try to teach me. I always wondered this miraculous linguistics, even if I had found it very hard to master. I am now making a research work on the linguistic differences between American and British English, hence I have been in love with US English since my childhood. Therefore, as my being a language examiner at one of the language examination boards, I am not only collecting pragmatic hints from my teaching practice, but I also would like to show some interesting points form the language exams. Moreover, I would really love to present some dialectical differences, which do inevitably utter pragmatics. For all this I have got to admit that an essay of some short pages could not fulfill the task to present every small bit of pragmatics, heedless of my honest efforts.
