You just opened a can of worms! Now that you asked for it, here is the answer:

Somehow we expect boys to be aggressive, domineering, and competitive, and we expect girls to be cooperative, nurturing, and, well, nice. But girls are not made of sugar! In reality, girls often show enormous signs of agression towards their friends. Their weapons -- gossiping, name-calling, excluding -- may not give other girls black eyes or bloody lips, but they can be as harmful as physical intimidation and violence.

As a college girl, you live in a world where best friends can become enemies overnight, where one look from another girl can mean the difference between isolation and belonging. It's a world where no one tells you why you can no longer sit at the lunch table with your friends, where secrets are traded like currency..

This is all normal. welcome to The Girls World!
