Quite a few tutors on this forum have mentioned being prepared to terminate tuition if, for whatever reason, it isn't working out. Very occasionally, I too have terminated tuition, and now I feel need to again. This time I am struggling to find the right words. Although I know to a certain extent in tutoring one has to take the rough with the smooth, with this particular student (or more particularly with his mother) I have just had enough. Partly it is because of three short notice cancellations this term: two have been for unexpected medical reasons, but this third time the mother really could have given me a lot more notice). But in addition the mother herself is demanding and difficult. Can any tutors out there who have ever found it necessary to terminate tuition suggest some non-blaming, diplomatic words I could use? I don't want to get into an argument with her, so don't want to be too specific as to reasons.
