DS7 has a new music teacher. She is very good, he really likes her and has improved a lot in a short period of time.
We went to her house for lessons a few times, and she has come to ours too. In at least three occasions she has brought her son (around 10yo). It was over the summer break so I thought she might be struggling with childcare. But now that the term started it has happened again.
The first time I could hear the boy on his phone from upstairs. I assumed he was in the kitchen talking, but DS told me later that he was in the same room with them. On the other occasions, he watched videos (with sound) on his phone and moved around the room quite a bit. His mum tells him to be quiet, but he it keeps happening.
DS didn't say anything at first but after the last lesson he said that he is finding it annoying and distracting.
I know I have to say something, I just don't know how to phrase it.
I don't want to upset her as she is lovely.
