Hi, I'm new...

Hi ladies, my name is Brittany!
I just downloaded this app out of curiosity, but after reading some of the comments and topics, I started wondering... Why don't we as (girls, women), why don't we talk to each other, like REALLY talk to each other? I've read some really interesting things, some personal, but still very informative. I think we all can benefit from "girl talk"; I guess what I want to know is why some girls/women are terrible friends? Why can't we all just stick together? Why is there always so much back biting and hate in the female community? I know that these are some tough questions (that's why I posted in this section), but I really want to hear from you ladies; why can't most women be good, honest, genuine friends to other women? Thoughts?
