Today I went back to the ballet school to teach , and found a whole load of novidades . First , the director warned me that she fired the ballet teacher for being incompetent , and I was just surprised it took her that long to notice . Apparently , she 's now teaching most of the ballet classes , though due to her schedule she ca n't be there all the time . Awesome . Next , I found that one of my top students , and one of the stars of the school , abruptly quit last week after some sort of petty argument .
Why would the narrator be struggling with the students .
