Politeness levels? Jaws or me?
Sadly, the written word, or perhaps to be a little more precise, the concept of communication through the use of symbols to represent sounds and concepts, is one of mankind's greatest achievements, it's also one of the banes of our species. No other form of communication exist that is so easily misunderstood, misinterpreted or prone to mistakes as the written word. It is fraut with not just accidental, but intentional misunderstanding; wars have been caused over the accidental use of a word, rifts have existed for centuries over what a phrase may mean.
As we move more and more into a world society that is more and more dependent on an ever growing disregard for language or interpersonal connections, the problem may reach a point beyond any recovery.
Having said all of that, if I have "said" anything that seemed inconsiderate or insulting, I must apologize for that. My intention is never to be intentionally offensive or insulting to anyone.
Of course, that isn't to say that I can't be intentionally offensive and insulting, but I'll tell you that I am being so intentionally.
