DD is in Y10 and - for the first time ever - I got an email from her school to say she had a detention after school (which is considered more serious than a lunchtime detention). She & her friend had been messing about on school trip taking photos on the coach of one of their friends, who was sitting on the seat in front.
The friend has gone home and complained to their mum, who's rung the school... which is why DD has a detention.
My message to DD is that her behaviour wasn't acceptable, she needs to say sorry to the friend (which she has).
DD has told me that prior to taking the photos, the friend sitting in the seat in front had been bouncing backwards on her seat to bash DD's knees.
When DD was told about detention, she didn't tell the teacher the friend had been bashing her knees because "it wouldn't have made any difference".
I've never got involved in any dramas previously, but for some reason I'm really annoyed DD (& her friend) have been punished - but the friend hasn't even had to apologise for her role in this. Probably because I've always taken the view with DD that she needs to try to sort friendship issues out herself (but obviously, I'm here if she ever felt bullied).
Just to be clear, there have never been any issues raised previously re. DDs behaviour - school reports have always been she's quiet and reserved.
Do I let it go or also complain to the school about the friend bashing DD's knees??
