I think that this quote by Ani DiFranco, who I don't really listen to but my sister does, sums up basic thoughts on female views of each other pretty well:
And God help you if you are an ugly girl
Course too pretty is also your doom
Cause everyone harbors a secret hatred
For the prettiest girl in the room
But then again, I tend to hang out with odd girls and men, I don't really care that much about how others look unless I'm in a snarky and critical mood, which happens about 5 times in a year
