If it's not broken,

If it's not broken, do not fix it.

Last week, 老梅子 claimed that her daughter was losing interests and she was thinking about switching teachers. Those questions were just popped up to me with those issues in mind. It is not that I am not willing to help you. Just do not feel right to answer your question, since I may put unnecessary doubts in your mind. Unless your child has particular problem, then it may worth the discussion. But still, it would be difficult. Without listening to and looking at the playing of the child, any guess could be way off base. However, appreciate that you trust me enough to ask the questions.
