Mary McBriar cannot understand what she did wrong. She was friendly to everyone in the school, she made sure to welcome all of the new students. She volunteered at all activities and stayed long after many had left. She thinks that she is attractive and always wears stylish and flattering clothing. She also has the highest grade point average in the school.
When the results of the voting for the Prom Court were announced, however, Mary did not see her name on the list. Instead, she saw the name of her sister and co-joined twin Terry. Terry is, according to her sister, the girl "who has a smart remark to and about everybody. She makes fun of what the new kids are wearing and just stands around drinking sodas and flirting with the teachers while I'm working on projects. She also dresses like a slut and is the only person I know who has ever flunked study hall or lunch."
When asked why she thinks that she was voted to the Prom Court, while her apparently more worthy sister Mary was not, Terry replied "Easy....I put out."
