When Marion Jones, the Olympic athlete, was in prison, “several inmates befriended her and showed her . . . how to hide sticks of butter.” Just as others carry water bottles so they can drink throughout the day, I carry butter in my backpack in a jar so I can eat small amounts throughout the day. As far as I know, no one else does this. I value butter so much because it makes my brain work better. If anyone reading this knows why inmates value butter so much, please let me know.
