Re: Is it proper?
I like Clarke's response the best so far. All I can add is that;
I had an instructor that I respect very much who changed his teaching style and the direction of the school. I spoke with him for a time about the changes in direction, and he really wasn't going to change back to what I preferred. So I keep in touch, and am still friendly, and visit the dojo maybe once a year, but I train elsewhere now. His school, his way, best of luck to all that I came up with there. No hard feelings...each person is doing what is best for them. 'Course, here in Philly there are a host of dojo that I can train at if I so desire. This all sounds easy now, but at the time it was quite difficult.
