He felts his smile slide away, melt, fold over and down on itself like a tallow skin, like the stuff of a fantastic candle burning too long and now collapsing and now blown out. Darkness. He was not happy. He was not happy. He said the words to himself. He recognized this as the true state of affairs. He wore his happiness like a mask and the girl had run off across the lawn with the mask and there was no way of going to knock on her door and ask for it back.
Ray Bradbury, Fahrenheit 451.
