Long story short, my 2nd year Uni student DD1 (20) moves out of her student house at the end of term tomorrow. I'm going to help her move her stuff. It's a house of 9 people and 4 of them (2 couples) have made her life completely miserable this last year, so much so that we've really worried for her mental health even though she is normally very resilient.
Too many instances of bullying to recount but includes calling house meetings to tell her how much they didn't like her, throwing her washing on the floor, leaving her locked out of the house when she forgot her keys etc etc. She has just tried to keep things polite and interact only when necessary, but they haven't let up and actively seek her out to be mean. Even this evening (her last night in the house) one of the boys knocked on her bedroom door at 11pm and when she answered, came into her room, told her he didn't like her and then ran away laughing. She's called me shaking and in tears.
I've bitten my tongue so far when I've seen them as DD1asked me not to say anything as she thought it could make things even worse. But after tomorrow she won't have to interact with them again. If I see them tomorrow AIBU to calmly tell them that their bullying behaviour has been toxic, caused extreme distress, is not OK and that in years to come they will look back and feel ashamed at how they've behaved?
