Mrs. Caravan is knowledgeable about the violin, but not in any way with dealing with children. She is not supportive as a teacher; she is constantly moody and she plays favorites, and both of these things add to the fact that she cannot communicate efficiently with her students. She knows how to play the violin, and she uses that quite often as a means of performing in her student's concerts. She is more concerned with herself or her favorites than the well being or performance of the class.
people need to show an interest in her class and practice so that she'll be nice
