The idea that the ugly girl is always the nicest or smartest girl. The idea that the beautiful girl is always shallow or mean.
I've read too much bad fan-fiction that relies on this tired stereotype, and it's hilarious. It usually reads like, "MagnoliaBeatrixIdony was a plain girl with brown hair and brown eyes, but she was very nice and very smart! ChanelLauren Vuitton was a blonde cheerleader and super popular, but she was very mean and treated Magnolia like dirt!" UGH. It's like a bad 80's sitcom, or something.
I don't agree with this one, though:
The discontented woman. Any time period, anything to be discontented over. Nuff said. Kwitcherbitchin.
A good story needs conflict, and a discontented character, male OR female, is essential. If all characters were perfectly content with their lives, no one would read the story.
