So I'm writing a Plot for a class and so far I have 3 girls who used to be best friends but got mad at each other over [Situation; like with a boy, each other, something idk] and haven't talked or seen each other in 6 years. They meet back up with each other at a mutual friends wedding and get stuck in an elevator together.

What is a good situation that would make three girls hate one another for years?
Also should the mutual friend be involved in the problem?

This is getting turned into an in class production so I would really like to it be thought out and logical!

Any and all help is appreciated! Thank you so much in advance!

I already gave you two suggestions, basically the same as your fellow student here. If you don't like those, I have no other ideas.
Unless you are not the same person as Radio Active Wear. My suggestions to that person were that one of them had spread nasty rumors about another one back in high school. The second was that one ran off and married another friend's boyfriend. smart1111 had a good idea that maybe one of them posted embarrassing videos about another one on the net.
Yes -- Kamera = Radio Active Wear
