What did Caroline say?
 

My Dad was speaking to me so I missed why she was called to the Diary room?

for bulling as usual. talking about housemates

It's just for her behaviour in general I think, they didn't mention specifics but the conversation was probably cut down and edited

About time too. She is non stop abusive. The venom she puts in her voice. She has said in the Diary room that she does not mean it. Well she can see the effect it has on other people so why does she not stop.
I can imagine her at school Awful girl.

Connors advice, never change. She will have to or be a bitter old woman. All she has to do is shut her mouth.
