VS, I didn't expect that you will take this as insult. Actually, the first ""dog"" in the proverb were you and I really want to stress that I don't want to insult you or somebody else. My disagreements are generally in connection with politics of overconfide between some administrators. The proverb describes this situation and for me is clearly that man who used it do not call ""dog"" anybody in the literal sense. So, I would like to ask for more confide to myself. I am not a ""criminal"" just because I am disappointed and keep  criticizing. Regards,   "
