"A mind is like a puzzle; you must unlock it to read its hidden secrets."

"Every Valentine's Day, the student council sponsered a holiday fundraiser by selling roses that would be delievered in class. The roses came in four colors:white, yellow, red, pink, and the subtleties of thier meaning were parsed and analyzed by the female population to no end. Mimi had always understood it thus:white for love, yellow for friendship, red for passion, and pink for a secret crush."
