How could I admit that the All-American Girl's force field of stoicism and self-reliance and do-unto-others-and-keep-smiling wasn't working, wasn't keeping pain and shame and powerlessness away? From a young age I had learned to get over - to cover my tracks emotionally, to hide or ignore my problems in the belief that they were mine alone to solve. So when exhilarating transgressions required getting over on authority figures, I knew how to do it. I was a great bluffer. And when common, everyday survival in prison required getting over, I could do that too. This is what was approvingly described by my fellow prisoners as 'street-smarts,' as in 'You wouldn't think it to look at her, but Piper's got street-smarts.
