It is bad to have hissy fits.
Sarah showed up to a big high school party wearing the same red dress as another girl.
Sarah wants her friends to think she's cool and fun to be around.
Sarah goes out of her way to be nice to the other girl all night.
Sarah throws her beer in the other girl's face and calls her a copycat c-word.
The next day Sarah's friends tell everyone she's the sweetest person they know.
Sarah is unceremoniously thrown out of the party by three members of the women's volleyball team, but her sycophantic friends all tell her she was totally justified.
