Tween Socializing

Max 3 This is my 10 year old… yes 10. Not 12 or 13.. but 10. Her and her friends are at each others throats every friggin day. She is bff with this one then bff with that one because the other one is too annoying or said something to offend her and the new bff. I can't keep up. Did we behave like this when we were pre teens ? Should I even care ? Should I intervene and give her some guidance on howto treat her friends ? Ahhh the joys of mothering just keep getting better with each day. Every time we think we're ahead of the game, something like the new found " tween" angst comes and kicks us in the ass.
