DDs are 15 (twins.)
They have a friend (A) and they have a bit of a love/hate relationship with her. Basically A was a good friend once but has gone off the rails a bit. But they have history with her.
A isn't always very good at taking care of herself. A few students noticed she had body odour and there were some unkind comments.
The teacher screwed her nose up and said 'someone needs deodorant.'
AIBU to think this is horrible?
