I believe it depend on the personality.
From a personal experience know many amazing women (average looking). Because they are confident, they shine with grace, kindness and respect. They treat other women nicely; however, I know few who make me come up with the UGLY WOMAN SYNDROM. The true ugliness was coming from their heart, bitterness and wickedness. They are very competitive in an evil way.
Competition with a dash of jealousy plain and simple.
They are crazy competitive psychos
its instinct its how they put other women in they place in the "child raising" part of they'r mind the "defend or befriend" tactic as is noted in psychology (or was it befriend or offend? i forget )
ah it was the "tend and befriend" study, if they cant befriend, they'll offend as its in the tend part of they'r mind
its a jealosy thing, plus women can be fickle at times.
Somehow they are so light minds and always driven by their wild instincts at the same time....it's nature, no big deal!
It's the nature of the b**** ...beast
we can be *******, so get over it we will
i dunno?!.......i wish they'd knock it off
Didnt know was an issue ...
