Why are females so nasty to each other?

Nazgol
I always thought it ends in high school but I was very surprised the hate, jealous , nastiness and gossip continues past beyond. Can they give each other a break? I mean I get jealousy and competition for guys, I was in the same boat and felt it too. But still... why can't women have a little bit more love for each other and not always strive to bring each other down?
