calling someone a stupid nobleman (nob is short for "A person in a superior position in life; a nobleman"), is not exactly nice. well, at least you pay him respect for his position. Calling him a prick though, is generally not the way we speak to each other on this forum, may even get you banned.
I can see you starting your training, sitting with the head of training, trying to be nice by calling him your nob, which he is of course, but what if he misinterprets and thinks you called him a prick?
To avoid confusion, I generally don't see threads that I started as mine, and even though criticism is not what I look for if I post, there may be some truth in it if several posters agree...
There is a wealth of valuable information on this site and you have been directed to it. Question answered, best of luck with the training. cheers IP
