Almost all girls experience some kind of bullying in their life, whether they were bullied or were the bully. I know that I have been the bully and the victim. My experience was very traumatic at the time. One of my best friends had written me a note. It was very common for my friends and I to pass notes all day at school.
Some girls can be just plain mean. Often operating under a "pack mentality," these girls isolate and banish their targets from the tribe, making them feel as if they don't belong. They gossip and start rumors and call the other girls names.
Girl bullying. Mean girls. Relational bullying. I recently gave a talk about bullying to a group of parents in my city. Afterward, a nervous-looking dad approached the front of the room to ask me a question.
