Y8 DC told me that one of the teachers made a derogatory comment towards another child who wouldn’t stop talking. It is the kind of comment that was common when I was in school in the 80s but is now rightly seen as disablist.
My DC was quite shocked at the comment as was older DC. It is possible that he misinterpreted the comment but not likely. I want to email school but as it is not my DC the comment was directed at would I be just seen as interfering?
