Polished, you sound like a fine teacher, and I have no disagreement with you. I was merely responding to the earlier post which reflected an often-used complaint by students who may not understand the process, and instead blame it either on a teacher's perceived lack of knowledge or a sales tactic, not believing that their teacher actually may know what they are talking about or have their best interests at heart. I have seen it happen to veteran, high quality teachers, and well as newer ones. It all boils down to trust.
And again I stress that if you don't trust your teacher, you need a new one and/or a new studio. You shouldn't wast your money and, more importantly, your time when you don't feel the value - regardless of the name of the studio. I feel the same about my students, and so should any other ethical teacher. I am sure you would agree.
