Just that really. I've had a bit of an experience with the same group of women. who decided they didn't like myself and another woman - we weren't friends with them and had done nothing (except try and organise something nice at school - this was before it had happened btw) The thing is at school and even at work I've never had any experience of women being mean to another woman for no reason. To qualify, I had female bosses I've disagreed with, and female friends whom I've had heated debates with and fallen out over - but it was something specific. No one picked on each other.
Where does this come from?
