I hate people like this. She's so full of herself that she doesn't realize that the ONLY reason she got that job is because she's attractive. She thinks she got it because she's intelligent and talented. It probably also hasn't occurred to her that her career has a VERY short shelf life. Not long from now, a younger and prettier girl will easily and quickly replace her. Typically, she'll see the writing on the wall and marry the first millionaire jock that asks her, and then get divorced a couple years later after he's had multiple affairs.
She's a mean girl now, was probably a mean girl in high school, and will probably be a mean old lady.
Gosh...I sound kinda bitter, don't I??
