DD (aged 15) has come home from school today saying that two of the girls in her group have announced they don't want to be friends with her anymore. I wouldn't normally get involved at all but we took dd, these two girls plus one other away to a festival last weekend and therefore got to know them all quite well. I am quite tempted to text one of them and ask if she has any idea why dd is so upset.
Is it ever worth getting involved or do I do as I usually do and leave well alone?
