At my DCs primary school it seems that majority of behaviour across all classes is quite good which I'm grateful for. Over the years a few times I have seen the teacher call over a few parents to talk to them about something their DC did that day. Last week I noticed the headteacher come out to speak to one of the parents which I haven't seen before.
My DC has told me on a few occasions he had to miss some of his break for being to noisy or chatty etc but luckily have yet to have a teachers chat about his behaviour!
Just generally nosy and curious as to how many time this has happened to you, and I wonder what the trigger is for teachers to decide this needs to be discussed with the parent.
