Oh yea and as a sidenote, maybe she was teaching you what she was supposed to teach you. I am assuming (I know I know ass out of you and me right?) that you were thinking her weaknesses were in technique..? At most studios the instructors must wait until (I know you hate to hear this) you pay for a certain program to teach you more than the basics. It may have been a missunderstanding on your part and you may have lost a great instructor..but it's not too late to come to her and explain yourself. Don't think I'm coming down on you, I may have made the same choice.
