I'm glad that you brought up the point about women being hard on other women. I though it was interesting when it was brought up in class that there wasn't much reaction. I think that women are so incredibly hard on one another. It absolutely astounds me. In the dorm that I live in it's very evident.
Girls take everything absolutely literal, therefore are much harder on each other.
I have no explanation for this or any idea why we treat each other this way. I think it's ridiculous and can't stand it, but some girls just thrive on this. On the fourth floor however, of guys, it's a much different story. Everyone more or less gets along, and if they don't they work on through it. So I definitely agree with Woolf and you about women being hard on other women.
