Yes, I know -- and that's one of the things that needs to go. That sort of relationship isn't healthy and only holds people and arts back.
This is true in all aspects of our lives. For example, many of us only have a "transactional relationship" with our co-workers but over time can develop a closer relationship.I'm pretty sure that for a majority (me included) they have/had a "transactional" relationship with our teachers. But over time the relationship could change to a much closer one. I think the term "master" is too loaded with the master/servant theme.
Quite frankly, IME most people get what they want. There are many people who want to be exploited (why I said it is an unhealthy relationship).I wouldn't seek a father figure in my teacher. I don't need one. But I would look for mutual respect in our relationship. I've heard of a lot of exploitative relationships btwn teacher and student.
As I see it, a WCK instructor should be like a personal trainer or a golf or tennis pro. They are there to service you, not you there to service them.
