Re: Respect/Lack there of.
I must apologize again, this time for apparently misunderstanding the point of your original post. I thought that you (and perhaps even your friend) were offended that he was not offered the chance to teach, given his greater rank, experience, and age. Now I see that was not the point. After reading your last post, I see that you are offended because you believe that our instructor that evening was annoyed with your friend's presence and treated him with disrespect. Now I see clearly what the disconnect is. You are simply incorrect in your assessment of the situation.
BTW, I did mention the dojo in question by name because I am a proud member of it, and I know it to be a place of utmost respect and wonderful training.
