Why do girls have conflicts with each other often?

Girls argue a lot, even if its over guys, nasty rumors and even make you feel lower than them. For example 2 best friends like the same guy, they will both fight until they get the guy. Some advice on that, would be let the guy make his own decision, and either way it plays out be happy with each other. In my opinion rumors are the worst that can come between friends at school. Girls don't understand how that makes other people feel. 85% of them are false, what leads to them is gossip. Gossip is casual or unconstrained conversation or reports about other people, typically involving details that are not confirmed as being true. There are other conflicts to, like you feel like your lower than your friend. Its typical to feel like this. Your friend thinks she has better clothes, a boyfriend, and you just hate being talked down to. Well, stand up for yourself have faith in yourself. Or be open to more friends who like the way you are. Girls do have a lot of fights during school hours, but if your really good friends you can make it through any fight.
