This student has been playing now for four years, and I am still in the process of building her technique and a broad base of knowledge before focusing efforts toward one style or another. I guess I'm frustrated that the parents are enabling her apparent laziness, and trying to pen her non-progress on me.Please offer any suggestions
Of course, that set of parents will probably never speak to you again (because of "frustrating" the "sincere study" of their proud and joy, undoubtedly because "you are jealous at real talent"), which may be a bonus....
