Piano lessons. He who will not hear must feel

For years now I have been trying to teach this spoilt brat to play the piano. For years I had the patience of a saint with her, but yesterday my neck finally burst. It can't be that she, at 19, still plays as if she were 10. From now on, other strings will be pulled. From now on, she has to go through the hard school and it can get a bit painful. But above all, it gets wet - very wet.
