I have been tutoring French for a very long time, this is the first time I have had a parent who sits at the table with me and their child. During the entire lesson they are interrupting by trying to correct their child's answers and pronunciation. The parent does not speak French, their corrections are not always wrong but are not always right either, either way it is affecting my ability to teach their child.
In addition to impeding my ability to teach the child, it is definitely making me uncomfortable. I would like to ask the parent if they could not sit with us the whole time, or maybe express that I would like to do the teaching by myself during the lesson (not have them interrupt with corrections). Again, this is the only child I have ever had in about ten years of professional tutoring who has done this!
Some specific issues I have in accomplishing this are that although neither mine nor the parents first language is English, we communicate in English. I struggle with speaking in English on the spot, and I would rather be able to send an email to the parent. I would like it to be polite and elicit their understanding, I don't want it to come across as confrontational.
For cultural context this is in Canada.
