Hi Behnam,
So you can see we are not the same!
Not only the words, but also the way man speaks has its own meaning. The ways can be so different that it may lead to some misunderstanding. In a live talk we use much more powrful and effective tool - body language, which is mimicry, gesture, eye expression, pose, tone of voice, etc. When we write, we use very poor, limited set - set of words. Don't overestimate word - it is a perfect instrument to confuse and decieve, but it very seldom let people come to agreement and understanding.
Must go. Continue later.
