This person has practiced for less than half the time I have. I have practiced for 13 years, I think he has for 4 or 5 now.
But the problem is that he is constantly belittling me. He treats me like a 6th kyu or something. Everything I say he says is wrong, or that my understanding is wrong. He posts on the aiki web and in the posts he acts like I am his student and he is a master. It drives me nuts, if my Sensei has promoted me to this rank I think Sensei would want me to be treated like the rank I am.
1) He sounds like an irritating person.
2) Rank really doesn't have anything to do with it. He'd be irritating no matter what the rank relationship
Anyway, IMO rank really shouldn't have anything to do with how you treat a person.
