Zanesville, OH - Tiffany McBeal, 15, came home upset about her chemistry class. "Mr Johnson told us about atoms and subatomic particles and stuff. We're made of mostly nothing. Even chocolate!" Her mother Karen knows that Tiffany wants to go to study nursing and is pretty smart. Unlike her sister Betty who went to hairdresser school. Karen remembers Betty studying the chemicals for dyeing hair and permanents, but they were real things, not this silly molecule stuff. "I don't know, soon Mr. Johnson will be telling Tiffany about evolutions and big bangs and such. Who does he think he is, with his master's degree? Even my husband has an accounting degree."
