I was sitting on the patio of the cafeteria late at night. My mouth was wide open but I could feel that my molars were cracking as if they were grinding on each other again. “How much longer is this place open?” I wondered. Three people were sitting at a round table a couple of meters away. They were talking about someone’s appearance who was apparently standing behind me. I resisted the urge to turn around to see who they were talking about.
