My oldest dd is in year 10. She has had 2 particularly close friend at school since last year and they naturally are a friendship group. However, towards the end of last year one girl, lets call her Alina, has asked her if she could hang out with her during breaks.
Alina had been kicked out of all friend groups and my dd felt bad for her, so she lets her hang out with her and her friends. This year, she has heard from her close friends that Alina has been bad-mouthing my dd with them.
According to dd, she has also been subtly excluding dd from group conversations, like only mentioning the other two with topics nothing specific.
The worst thing is, due to a standard school lock policy at school, dd needs to use the lock provided by the school, which she struggles with. Therefore, when there isn't enough time, she would leave her locker unlocked.
Everytime this happened, Alina would throw her hat in the mud at the very corner of the school near the locker room. dd is very upset about this but as there is no camera on that spot and there isn't more evidence than what Alina said to her two close friends, nothing can be done about it.
dd is very angry that Alina is still telling people to kill themselves on Roblox, despite her asking her not to for many times.
dd's two close friends don't like Alina very much either but Alina is decent to them so they don't mind being friends with Alina as well. They are reluctant to have a conversation with Alina for not hanging out with her anymore because they are too scared to and just don't know how to. dd is leaving the group and staying with her other friends. She will lock her locker at all times after.
